similar to: [LLVMdev] How to write a regression test case?

the example is more like what i need,it is so nice. but,i am indefinite if "RUN: FileCheck < %t.s %s" can pass,i understand that t.s was translate from t.ll,%s means read the local source,are they the same?

Wang, Attachment is a simple example, you may put it in test/CodeGen, and run with llvm-lit C90 It worked ok in my llvm 3.2 devel. Let know if you run into any trouble.

hi,Yang: if you can give me a examle,which check out a string(such as "abcd") from a file(such as aaa.c) with fileCheck? i tried to write it but failed. thanks for your help! best wished! changcheng On Wed, Aug 22, 2012 at 9:30 PM, Triple Yang <triple.yang at gmail.com> wrote: > I guess so. > FileCheck has powerful extensions than just matching some strings so that >

You are welcome. /* example.c */ // RUN: clang %s -S -O0 -emit-llvm -o %t.ll // RUN: llc %t.ll -O0 -march=x86 -o %t.s // RUN: FileCheck < %t.s %s // CHECK: fct unsigned int fct(unsigned int n) { if(n>0) return fct(n-1)*n; else return 1; } /* end example.c */ /* lit.local.cfg */ config.suffixes = ['.c', '.cpp', '.ll'] targets =

hi,yang: sorry to trouble you another time,i used your example and it run well,but a problem came,it create severel temporary files i chaged the RUN: line but failed. i changed it like this,can you give me some suggestions? // RUN: clang %s -S -emit-llvm | llc -march=c | clang -S -emit-llvm | lli | FileCheck %s thanks, best wishes, changcheng On Wed, Aug 29, 2012 at 8:39 AM, Changcheng Wang

hi,yang: i had delete the temporary files,sorry to trouble you. it is so easy: // RUN: rm ....

hi,yang: thanks,i replaced "{helloworld}" with "helloworld" as you said,and the test run well on llvm version 3.0,but fail on llvm 162227,is it right? llvm version 162227 do not support it? your, changcheng On Tue, Aug 28, 2012 at 2:28 PM, Triple Yang <triple.yang at gmail.com> wrote: > 2012/8/28 Changcheng Wang <changcheng at multicorewareinc.com>: >>

aha, that's quite straightforward. 2012/8/29 Changcheng Wang <changcheng at multicorewareinc.com>: > hi,yang: > i had delete the temporary files,sorry to trouble you. > it is so easy: // RUN: rm .... > > Regards > changcheng > > On Wed, Aug 29, 2012 at 2:41 PM, Changcheng Wang > <changcheng at multicorewareinc.com> wrote: >> hi,yang: >> how

hi,yang: another question，i write a test like this: /*****test start******/ ; RUN: llc -march=c < %s | FileCheck %s ; ModuleID = 'hello.c' 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-S128" target triple = "x86_64-unknown-linux-gnu" @.str = private

I did an experiment just now with a test case like: // RUN: clang %s -S -emit-llvm -o %t.ll // RUN: llc %t.ll -o %t.s // RUN: FileCheck < %t.s %s ... // CHECK: ... And it worked. It seems clang does not take stdin as its input, so "clang < %s" fails. Meanwhile, both "llc < %t.ll" and "llc %t.ll" work. 2012/8/22 Triple Yang <triple.yang at

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

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
