similar to: [LLVMdev] if you can give me an example?

thank yang,thank Wei-Ren! i feel i am a question boy,because i has another question now. i want to check if a program output right result,which example in llvm/test/* can give me some idea? suppose i have a helloworld program if it run well,it can give me a result "helloworld",so i want to check if the result is "helloworld". best wishes! changcheng On Tue, Aug 28, 2012

hi,chen: thaks for your explaining,after reading it i have a few problems more. 1.in the sentenses of "X32: subl $-128, %eax" and "; X64: subl $-128," ,i do not know what means that in detail,these sentences were writen follow which language rules? 2.i want to write such a test:translate a *.ll(i.e:hello.ll) file to a *.c file(i.e:hello.c) with llc,then verify if the .c

Hi Changcheng, Below is an example took from test/CodeGen/X86/add.ll: define i32 @test1(i32 inreg %a) nounwind { %b = add i32 %a, 128 ret i32 %b ; X32: subl $-128, %eax ; X64: subl $-128, } 1. The first step, you write a function by using LLVM IR. define i32 @test1(i32 inreg %a) nounwind { %b = add i32 %a, 128 ret i32 %b } This will be left to LLVM toolchain to generate

Hi Changcheng, The question you ask seems to be a different topic from this thread. If possible, I sugguest you lauch another thread so that people know what you want to ask by looking at subject. Since you're working on C backend, you may want to collaborate with Roel, who is working on C backend, too [1]. Regards, chenwj [1]

> 2) I had no problem running the V3.0 regression tests according to the instructions. However, the instructions in the Testing Infrastructure Guide for running the Test Suite presume the existence and use of llvm-gcc, http://llvm.org/docs/TestingGuide.html, both on-line and in the rc4 kits. Now that llvm-gcc is gone for V3.0, it isn't completely obvious how to run the test-suite

Hi,all: i have a question about llvm162227,recently i have a work about cBackend,i found a the Module data is different from llvm2.9,a pass named CBackendNameAllUsedStructsAndMergeFunctions() was removed.for this the module data can not be translated correctly. when i try to rewrite this pass,i found much interfaces of module have been changed. i write a test which contian a struct like this

aha,i add cBackend into llvm version 162227,my test run passed. it so hapyy! thanks for all of you! still a question: what does "; PR1028" means? best wishes, changcheng On Tue, Aug 28, 2012 at 2:35 PM, Changcheng Wang <changcheng at multicorewareinc.com> wrote: > hi,yang: > > thanks,i replaced "{helloworld}" with "helloworld" as you said,and the

Mr. Chen, The link is out of date, please go to http://ccckmit.wikidot.com/ and select LLVM row in the table. My first version book is put on my brother's web site. Now, I create my Dropbox link.

In other words, this test case guarantee that pr1028 will not back again. If so, it will fail.

Hi, Sorry I did not precise that, but I'm already doing that... I have, as you say, two different director, one for source and one for build (where I run my configure)...

Removed from trunk. Pawel can decide if its necessary to update the tarballs. Thanks for the report! Apparently git-svn does not delete removed directories.

Right, I forgot to update that originally. I also have a separate document in the works that goes into more detail for NVPTX.

I suggest u grep how this file is used. Since it is included in xxInstrInfo.td and this is its only use, we can conclude that this file does nothng more than defining some helper tablegen classes and we thus can totally move these definitions into xxInstrInfo.td and then remove XXInstFormat.td Regards. 在 2013-2-6 下午4:52，"陳韋任 (Wei-Ren Chen)" <chenwj at iis.sinica.edu.tw>写道： >

Hi, thanks for your letter,but i have read it several times,and now i am confused still.because i do not know how the test work. for a simple sample: ; RUN: llvm-as < %s | llvm-dis | FileCheck %s @addr = external global i64 define i64 @add_unsigned(i64 %x, i64 %y) { ; CHECK: %z = add nuw i64 %x, %y %z = add nuw i64 %x, %y ret i64 %z } 1.FileCheck verify the file that llvm-dis output and
