I'm getting some problems because it seems that the compiler is treating "floor" differently from other math library functions like "sin". The Args and RetVal have the parameter and return types marked as void. For mips16, it's important that I be able to know the original signature for floating point functions. In some cases, need to create calls to helper

I need to be able to emit .globl for the soft float routines used by mips16. The routines are called but there is no .globl definition for them. How can I do this? Background: I have a strange issue that I encountered with mips16 hard float. Part of mips16 hard float is to emit calls to runtime routines with the same signature as usual soft float routines, except that they are implemented

Hello everybody, I have stumbled upon a test case (the attached module is a slightly reduced version) that shows extremely reduced performance on linux compared to windows when executed using LLVM's JIT. We narrowed the problem down to the actual code being generated, the source IR on both systems is the same. Try compiling the attached module: llc -O3 -filetype=asm -o BAD.s BAD.ll Under

...rently that???s why I don???t see the prints.

Until version 5.01 I can boot as usual with no issues. However, when I use pselinux.0 version 5.02 and up, the following problem happens: 1. My PXE driver loads and the links are up 2.

(I?m using syslinux-6.03-pre02) printf () or dprintf ()? You need to watch what functions are available at the time you want to print. For example, printf isn't available until ldlinux.c32 is

Hi, These patches contain support for some features that are already in Syslinux 4 but weren't working properly on the elflink branch. It's another step closer to feature parity with Syslinux 4. Having to jump through the comboot API for localboot support is less than ideal and I'll eventually fix that, probably when we move a big chunk of code from asm to C. Also, there's a

Which part of the generated code do you think is not correct? Could you be more specific? I compiled this program with clang and ran it on a mips board. It returns the expected result (21).

I check the Mips backend for the following C code fragment compile result. It seems not correct. Is it my misunderstand or it's a bug. //ch8_3.cpp #include <stdarg.h> int sum_i(int amount, ...) { int i = 0; int val = 0; int sum = 0; va_list vl; va_start(vl, amount); for (i = 0; i < amount; i++) { val = va_arg(vl, int); sum += val; } va_end(vl);

Hello everybody, setting up a netboot server for a really huge network I decided to go with what will be syslinux 4.10 to get support for http transfers. The setup works on my notebook, booting another notebook directly connected. However it fails with a more complex setup: A virtual machine on the second notebook bridged to the ethernet device does not boot, systems from other networks with a
