Compile not optimized Libgcc for ARM
Good morning,
I need to compile libgcc from scratch without deploying the ARM optimized version which is defined in ieee754-sf.s in the ARM back-end. Does anyone knows how to configure GCC for excluding ieee754-sf.s ( in libgcc/config/arm ) to compile from scratch libgcc, in particular compiling vanilla floating-point soft-fp emulation which is in libgcc/spft-fp ?
Thanks

How gcc optimize sum from 1 to 100 into 5050
I compiled following c program with
gcc -O3 -S a.c:#include <stdio.h> int main() { int sum = 0; for (int i = 0; i <= 100; i++) { sum += i; } printf("%d", sum); }The generated assembly code is as follow:
.section __TEXT,__text,regular,pure_instructions .build_version macos, 10, 15 sdk_version 10, 15, 4 .globl _main ## -- Begin function main .p2align 4, 0x90 _main: ## @main .cfi_startproc ## %bb.0: pushq %rbp .cfi_def_cfa_offset 16 .cfi_offset %rbp, -16 movq %rsp, %rbp .cfi_def_cfa_register %rbp leaq L_.str(%rip), %rdi movl $5050, %esi ## imm = 0x13BA xorl %eax, %eax callq _printf xorl %eax, %eax popq %rbp retq .cfi_endproc ## -- End function .section __TEXT,__cstring,cstring_literals L_.str: ## @.str .asciz "%d" .subsections_via_symbolsAs if GCC ran the code and notice that the loop times are determined and GCC replaced the whole calculating with the result 5050.
movl $5050, %esiHow does gcc do this kind of optimization? What's the academic name of this kind of optimization?

Use of empty tag struct, compiler claims I'm missing initializer, except I'm not
Okay, I know this is similar to this Why is the compiler throwing this warning: "missing initializer"? Isn't the structure initialized?, but surely GCC isn't stupid enough to think I meant to initialize something which has NO initialization?.
//main.cpp struct IsNamed{ }; template<typename T> struct Test{ int foo; }; struct Test2 : public Test<double>, public IsNamed{ }; int main(){ Test2 x; Test2 y = Test2{Test<double>{}}; return 0; }Here's the output:
main2.cpp: In function 'int main()': main2.cpp:18:35: warning: missing initializer for member 'Test2::<anonymous>' [-Wmissing-field-initializers] 18 | Test2 y = Test2{Test<double>{}}; | ^ main2.cpp:16:11: warning: unused variable 'x' [-Wunused-variable] 16 | Test2 x; | ^ main2.cpp:18:11: warning: variable 'y' set but not used [-Wunused-but-set-variable] 18 | Test2 y = Test2{Test<double>{}}; |The only warning I'm confused about is this " missing initializer for member 'Test2:: " warning. It makes no sense. There's only one possible value I would need, and I provide it. Just to prove that it is indeed the inclusion of the empty class in the inheritance chain that is causing this, here's the output if I remove it:
main2.cpp: In function 'int main()': main2.cpp:16:11: warning: unused variable 'x' [-Wunused-variable] 16 | Test2 x; | ^ main2.cpp:18:11: warning: variable 'y' set but not used [-Wunused-but-set-variable] 18 | Test2 y = Test2{Test<double>{}}; |People say just ignore it, but it's not feasible for my project. I've got lots of classes with this error that follow the same tag struct pattern. It's not reasonable to selectively disable this warning (I also find it useful in other circumstances).
How do I get the compiler to stop complaining about this? I should also mention that
Test2{Test<double>{},{}};would not be an appropriate solution, as I have template code in use where some of the classes do not have this problem, and some do, which means this becomes an error in those circumstances.EDIT:
Note here is the example CMake used, which included the compiler options:
cmake_minimum_required(VERSION 3.13) project(test) set(CMAKE_CXX_STANDARD 17) set(CMAKE_C_STANDARD 11) add_executable(test main.cpp) target_include_directories(test PRIVATE ./ ) target_compile_options(test PRIVATE $<$<OR:$<CXX_COMPILER_ID:Clang>,$<CXX_COMPILER_ID:GNU>>: -Wall -Wextra -Wshadow -Wnon-virtual-dtor -pedantic -g -ggdb -O1>)I'm also using mingw64-10.2

PHP division adds a comma
I'm trying to convert cents to dollars (I don't need dollar sign, just value) but when I divide a number smaller than 100 by 100 I get a strange result.
Eg.: 1/100 give me 0,01.0
I don't need that comma, I need 0.01 as it should be.
I also tried number_format but it returns a string and when I cast the result to float I get the same strange value.
How can I fix it?
Thanks in advance for your help
This is the function I'm using:
public static function convertFromCents($value) { if(is_numeric($value)) { $value = $value/100; } else { $value = 0; } return $value; }This are the proof of what I'm saying:

Scaling down block drawing without one block fighting to be two things
The code I lost in a hard drive failure however over a year later it still bugs me about it and I really want an answer so I can sleep at night without this popping into my head. So I was writing a defragmentation software and it displayed the clusters. The problem with the drawing code is floating point math. I'm not experienced enough to solve this math problem. I could draw the clusters no problem however due to floating point math the last pixel were fighting with the first pixel of a new cluster when I scaled it down to fit a window. I can't figure out how to prevent this. I tried rounding down and up but that left a pixel either empty or overwriting a pixel f the last cluster when it shouldn't be, etc. It should look like this. Can't figure out how this JkDefrag (open source) did it and I have the source code for it! This is what keeps me up at night. Please help me get a good nights sleep.

How to *reverse* JavaScripts DataView?
I understand this question is oddly phrased, so let me explain with 2 examples.
Example 1
The code below turns the series of values[64, 176, 0, 86, 68, 97, 136, 8]into the float4096.336980910979.(new DataView(new Uint8Array([64, 176, 0, 86, 68, 97, 136, 8]).buffer)).getFloat64(); /*Output 4096.336980910979*/How do I reverse it to get the series of values
[64, 176, 0, 86, 68, 97, 136, 8]when I input the float4096.336980910979?Example 2:
The code below turns the series of values[70, 253, 192, 0]into the float32480.(new DataView(new Uint8Array([70, 253, 192, 0]).buffer)).getFloat32(); /*Output 32480*/How do I reverse it to get the series of values

undefined reference error when building program using shared library that link static library
I built AWS WebRTC library as static library and made some shared library using it. As I understand, the static library should be included to the shared library if I make the shared library with the static library. But "undefined reference to ''" error(about the WebRTC library) happens if I build a program using the shared library.

Real world DRAM write only application
I am eager to know if there is any real world application which includes following scenario:
Megabytes of continuous write-only to DRAM simultaneously from all (three or more) A53 cores (or any other Arm cores) – throughout the application as the only operation from the core.
The reason why I am asking is, I came accross a specific scenario while designing a chip in which the above operation is misbehaving, so would like to explore how to handle this specific scenario if it's valid.
I could think of only DRAM initialisation.

Why this function does point to itself with a offset of 1?
I'm trying to write a bare metal blink program for a Nucleo-64 Stm32F401re board using C. However while starting debugging for errors (it didn't blink yet) I found an odd adress for which I found no explanation. This is the output of the relevant part of the disassembly:
blink.elf: file format elf32-littlearm Disassembly of section .text: 08000000 <isr_vector_table>: 8000000: 20018000 andcs r8, r1, r0 8000004: 08000009 stmdaeq r0, {r0, r3} 08000008 <Reset_Handler>: 8000008: b480 push {r7} 800000a: af00 add r7, sp, #0 800000c: bf00 nop 800000e: 46bd mov sp, r7 8000010: bc80 pop {r7} 8000012: 4770 bx lr Disassembly of section .ARM.attributes: 00000000 <.ARM.attributes>: 0: 00002d41 andeq r2, r0, r1, asr #26 4: 61656100 cmnvs r5, r0, lsl #2 8: 01006962 tsteq r0, r2, ror #18 c: 00000023 andeq r0, r0, r3, lsr #32 10: 2d453705 stclcs 7, cr3, [r5, #-20] ; 0xffffffec 14: 0d06004d stceq 0, cr0, [r6, #-308] ; 0xfffffecc 18: 02094d07 andeq r4, r9, #448 ; 0x1c0 1c: 01140412 tsteq r4, r2, lsl r4 20: 03170115 tsteq r7, #1073741829 ; 0x40000005 24: 01190118 tsteq r9, r8, lsl r1 28: 061e011a ; <UNDEFINED> instruction: 0x061e011a 2c: Address 0x0000002c is out of bounds.The Reset_Handler function itself is on the right adress but by using its name as pointer in the code it points one adress further! Here is the corresponding code:
extern int _stack_top; // bigger Memory Adress void Reset_Handler (void); __attribute__((section(".isr_vector"))) int* isr_vector_table[] = { (int*)&_stack_top, (int*)Reset_Handler }; void Reset_Handler (void) { }And the Linker script I used which is basically the same used in most tutorials.
OUTPUT_ARCH(arm) OUTPUT_FORMAT("elf32-littlearm", "elf32-bigarm", "elf32-littlearm") ENTRY(Reset_Handler) MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 512K SRAM (rwx) : ORIGIN = 0x20000000, LENGTH = 96K } _stack_top = ORIGIN(SRAM)+LENGTH(SRAM); SECTIONS { .text : { . = ALIGN(4); *(.isr_vector) *(.text*) *(.glue_7) *(.glue_7t) *(.eh_frame) KEEP(*(.init)) KEEP(*(.fini)) . = ALIGN(4); _etext = .; } > FLASH .rodata : { . = ALIGN(4); *(.rodata*) . = ALIGN(4); } > FLASH .ARM.extab : { *(.ARM.extab* .gnu.linkonce.armextab.*) } >FLASH .ARM : { __exidx_start = .; *(.ARM.exidx*) __exidx_end = .; } >FLASH .preinit_array : { PROVIDE_HIDDEN (__preinit_array_start = .); KEEP (*(.preinit_array*)) PROVIDE_HIDDEN (__preinit_array_end = .); } >FLASH .init_array : { PROVIDE_HIDDEN (__init_array_start = .); KEEP (*(SORT(.init_array.*))) KEEP (*(.init_array*)) PROVIDE_HIDDEN (__init_array_end = .); } >FLASH .fini_array : { PROVIDE_HIDDEN (__fini_array_start = .); KEEP (*(.fini_array*)) KEEP (*(SORT(.fini_array.*))) PROVIDE_HIDDEN (__fini_array_end = .); } >FLASH . = ALIGN(4); _sidata = LOADADDR(.data); .data : { . = ALIGN(4); _sdata = .; *(.data*) . = ALIGN(4); _edata = .; } > SRAM AT > FLASH .bss : { . = ALIGN(4); _sbss = .; __bss_start__ = _sbss; *(.bss*) *(COMMON) . = ALIGN(4); _ebss = .; __bss_end__ = _ebss; } > SRAM /DISCARD/ : { libc.a ( * ) libm.a ( * ) libgcc.a ( * ) } .ARM.attributes 0 : { *(.ARM.attributes) } }So why the adress stored in the isr_vector_table is 08000009 and not 08000008? The only way I so far could change it to the right value was through hardcoding the value or defining a extra section for the Reset_Handler so I could use the adress as another extern value like the _stack_top.
Here are the commands I used for compilation as I don't know if they are necessary to find an answer:

why am I getting a precise bus fault exception (PRECISERR) on what looks like a perfectly fine aligned access (cortex-m7)
I'm getting a HardFault that results from a forced/escalated Precise Bus Fault Exception, as indicated by the

.textsection in my linker file, as shown belowMEMORY { m_interrupts (RX) : ORIGIN = 0x00000000, LENGTH = 0x00000400 m_text (RX) : ORIGIN = 0x00000400, LENGTH = 0x00074000 /* changed from LENGTH = 0x0003FC00 */ m_data (RW) : ORIGIN = 0x20000000, LENGTH = 0x00020000 m_data2 (RW) : ORIGIN = 0x20200000, LENGTH = 0x00020000 }If it isn't an alignment issue, I'm not sure what it could be? But
0x00040458is most definitely word-aligned, as is0x0004045Cwhich results from the#4offset to theldrinstruction.Also, why is
0x0004045Cnot shown inBFAR, since the cortex-m7 TRM says theldrinstruction applies the offset to the target register value before the memory access occurs??Full exception registers shown below for completeness

How to change exception priority on cortex-m4 processor in Rust?
I want to set interrupt priorities for processor internal exceptions. The
cortex_mcrate provides easy access to NVIC control registers. Specifically, there is a method that let me set priority for each interrupt.let mut p = cortex_m::Peripherals::take().unwrap(); p.NVIC.set_priority(...);set_priorityasks me to pass an argument specifying for which interrupt I intend to modify the priority. Say I want to change the priority forPendSV. However, passing incortex_m::peripheral::scb::Exception::PendSVwill not work because it does not implement a required trait bound.I am developing on STM32F407VGT6 board, so I also looked in the
stm32f4crate, but I did not find any enum definition that can help either.Should I write my own enum that implements the required trait so that it can specify interrupt numbers, or is there already some existing crate that can make it work?
