I try to generate a human readable .ll file on Linux. I installed llvm-gcc
but as I see it can generate only assembly code (-S option). Is there any
way to get something like what is generated by llvm online compiler?
That's what I get with llvm-gcc -S -emit-llvm hello.c on Ubuntu 10.10:
.file "hello.c"
.ident "GCC: (Ubuntu/Linaro 4.5.1-7ubuntu2) 4.5.1 LLVM: "
.text
.globl main
.align 16, 0x90
.type main, at function
main:
pushl %ebp
movl %esp, %ebp
subl $8, %esp
movl $.L.str, 4(%esp)
movl $1, (%esp)
call __printf_chk
xorl %eax, %eax
addl $8, %esp
popl %ebp
ret
.Ltmp0:
.size main, .Ltmp0-main
.type .L.str, at object
.section .rodata.str1.1,"aMS", at progbits,1
.L.str:
.asciz "hello world\n"
.size .L.str, 13
.section .note.GNU-stack,"", at progbits
That's what I am trying to get:
; ModuleID = '/tmp/webcompile/_7829_0.bc'
target datalayout
"e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64"
target triple = "x86_64-linux-gnu"
@.str = private constant [12 x i8] c"hello world\00", align 1 ;
<[12 x i8]*>
[#uses=1]
define i32 @main() nounwind {
entry:
%0 = tail call i32 @puts(i8* getelementptr inbounds ([12 x i8]* @.str, i64
0, i64 0)) nounwind ; <i32> [#uses=0]
ret i32 0
}
declare i32 @puts(i8* nocapture) nounwind
On windows I successfully get this file with the same command: llvm-gcc -S
-emit-llvm hello.c.
