similar to: [LLVMdev] Directive parsing for AsmParser

Hi Daniel, attached is a patch that pushes most of the object file specific parsing out of AsmParser and down into MachOAsmParser. This was done as a cleanup for the ELF work. I know that you're not happy with this approach, particularly the fact that as we add more object file formats and assembler dialects, it's going to cause a class explosion. But I was hoping that we could use this

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.

Rails 3.1.3 I''m trying to pass a value to ''save.js.erb'' . in the view, I have put <%= hidden_field_tag "video-id", @video.id, { :id => "video-id" } %> then, I can retrieve it by var idval = $(''#video-id'').val(); It certainly gets the value. The problem is then I need to pass it to the following. I tried,

I was told that I can use clang + llvm to get MIPS instructions on my x86 machine. I did following command and got error below. Does anyone have any idea ? or can someone suggest me how to get MIPS instructions easily from llvm. clang -ccc-host-triple mips-unknown-linux -ccc-clang-archs mips helllo.c clang: warning: unknown platform, assuming -mfloat-abi=soft '+' is not a recognized

Hi LLVM developers, GCC[1] is able to use Loongson ISA[2] for instruction selection: $ cat hello.c #include <stdio.h> int main(int argc, char *argv[]) { printf("Hello World\n"); return 0; } $ gcc -O0 -S hello.c $ cat hello.s .file 1 "hello.c" .section .mdebug.abi64 .previous .nan legacy .gnu_attribute 4, 1 .abicalls

Hello everyone. I use this command clang -emit-llvm hello.c -c -o hello.bc llc hello.bc -march=mipsel -relocation-model=static -o hello.s to produce this MIPS code: .section .mdebug.abi32 .previous .file "hello.bc" .text .globl main .align 2 .type main, at function .set nomips16 # @main .ent main main: .cfi_startproc .frame $sp,32,$ra .mask 0x80000000,-4 .fmask

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:

- my old email address. The ISA_* classes might not be the best choice for this. There's an overall hierarchy and ordering to the ISA_* classes since they represent the generations of the MIPS ISA. If these extensions are available in Loongson chips based on MIPS32r1 and MIPS32r2 for example, it becomes difficult to describe with ISA_* classes without duplicating instruction definitions or

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

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);

Sorry if this is a duplicate: I tried to send it last night and it didn't go through. I'm trimming some text to see if it helps. I have a simple program that fails on the Microblaze: int main() { unsigned long long x, y; x = 100; y = 0x8000000000000000ULL; return !(x > y); } As you can see, the test case compares two unsigned long long values.

I'm just passing this patch on to the list as I know Brian is busy and I had proded him to file the bug report. http://llvm.org/bugs/show_bug.cgi?id=14721 "binutils on OpenBSD is quite old, which causes the build on mips64el to fail on MipsJITInfo.cpp - it complains of illegal operands. The attachment patches it so that it will build. All the patch does is replace the register aliases
