similar to: [LLVMdev] floor

Here is a test case: extern double floor(double); extern double floor_(double); double x = 1.5; double y, y_; void foo() { double y = floor(x); double y_ = floor_(x); } If I compile this for Mips16, it calls the proper helper function for floor_ but not for floor, because the signature for floor in callee info is wrong. Args[0] = void RetTy = void

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

I didn't have Mips board. I compile as the commands and check the asm output as below. 1. Question: The distance of caller arg[4] and arg[5] is 4 bytes. But the the callee get every arg[] by 8 bytes offset (arg_ptr1+8 or arg_ptr2+8). I assume the #BB#4 and #BB#5 are the arg_ptr which is the pointer to access the stack arguments. 2. Question: Stack memory 28($sp) has no initial value. If

Does it make a difference if you give the "-target" option to clang? $ clang -target mips-linux-gnu ch8_3.cpp -o ch8_3.bc -emit-llvm -c The .s file generated this way looks quite different from the one in your email.

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);

Hi, I am hoping that someone can help me figure out how to prevent the insertion of "memcpy" from the assembly source. My target is an instruction set simulator that doesn't support this. Thank you for your valuable time. Wolf *Here are my compile commands:* $ clang -emit-llvm -fno-builtin -o3 --target=mips -S matrix_float.c -o vl_matrix_float.ll $ llc vl_matrix_float.ll *IR

Hi, > Can you post the llc command line you're using? Can you post an LLVM IR > file that causes this behavior? yes: ${LLVM_PATH}/bin/llc -o helloworld.s -march=nvptx helloworld.ll where LLVM_PATH my local installation path for LLVM. Also attaching helloworld.c: #include <stdio.h> int main(void) { printf("Hello World!\n"); return 0; } and helloworld.ll:

Alright, couple of points here: 1. Address space 0 is invalid for global variables. This is causing a crash in llc where we use llvm_unreachable() on this case. This is most likely why you're seeing llc run forever. The fix for this is to use address space 1 for globals, which puts them into PTX global memory. On our side, we should provide a meaningful error message in this case. 2. The

Hello, clang/llvm 4.0.0 generates invalid calls for builtin functions with -mfloat-abi=hard -ffast-math. Small example fail.c: // clang -O2 -target armv7a-none-none-eabi -mfloat-abi=hard -ffast-math -S fail.c -o - extern float sinf (float x); float sin1 (float x) {return (sinf (x));} generates code to pass the parameter in r0 and expect the result in r0. The same code without

Hi, I wonder if anybody could help me in converting this easy SAS program into R. (I'm still trying to do that!)

Hi, I noticed that klibc started crashing on 64-bit MIPS and in my quest to fix the bug I got a bit carried away and fixed a few other things as well. Here are various miscellaneous MIPS patches, although the first patch is the important one. Thanks, James *** BLURB HERE *** James Cowgill (5): mips64: compile with -mno-abicalls mips: use -Ttext-segment when linking shared library

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

Hello, You know, I always worry about the precision and the float constants... and there is a large lookup table in the floor1.c ... and I figure out a way to keep the code size and speed, but to improve the precision at this lookup table. (the difference is small, but audible) Here is the modifications in the floor1.c: tatic unsigned long FLOOR_fromdB_LOOKUP[256]={

Hello, I have two questions concerning floor1 encoding/decoding. First I'll ask about the FLOOR1_fromdB_LOOKUP table: what is it's purpose? Is it to convert the amplitude differences between [floor1_Y] values to a dB scale? And, if I'm right with that, here comes the 2nd question: when render_line0 is used to encode floor1, then floor1_inverse2 must be used in decode (in order to
