similar to: [LLVMdev] LLVM +stdcxx

I tried to compile LLVM + stdcxx and I got a lot of compiling errors. Did anyone got that? Manoel Teixeira

%FIRSTSTRU = type { i32, double, i32, i8* } struct { int var1; double var2; int var3; char *var4; }firstStru ; Could someone help? If, running a application in windows with MSVC, I allocate a memmory buffer and call a LLVM function with such buffer, there's a structure alignment problem. If the LLVM function call a C function using the same buffer, it runs fine. Any ideas?

struct xfirstStru { int var1; double var2; int var3; char *var4; }; %FIRSTSTRU_PLUSPLUS_TOTVS. = type { i32, double, i32, i8* } Hi, I had not applied the layout at run time, only during the emission of the .bc. Now it's running ok when I allocate the structure point at LLVM side, but, when I allocate the structure pointer in the C

1. Re: LLVM optmization (Bill Wendling) Hi, The IR is not wrong. I said that the assembler generated by MSVC is quicker. We can see that the for loop, in the TESTE function, is done without jump's in the MSVC and with jumps in LLVM. I think thats the point. If we don't use threads, the result is the same. My test were done with one billion interactions in the for loop. The MSVC

Hi, It's not ok yet. When a C function calls a LLVM function, or a LLVM function calls a C function, the offset of the variables are wrong. When a don't mix LLVM with C, it's ok, but I need call extern functions using structs.

The following C code : #include <stdio.h> #include <stdlib.h> int TESTE2( int parami , int paraml ,double paramd ) { int varx=0,vary; int nI =0; //varx= parami; if( parami > 0 ) { varx = parami; vary = varx + 1; } else { varx = vary + 1; vary = paraml; } varx = varx + parami + paraml; for( nI = 1 ; nI <= paraml; nI++) { varx =

The following C test program was compiled using LLVM with -O3 option and MSVC with /O2. The MSVC one is about 600 times faster than the one compiled with the LLVM. We can see that the for loop in MSVC assembler is solved in the optimization pass more efficiently than that in LLVM. Is there an way to get a optimization result in LLVM like that of the MSVC?

Hi, I'm trying to use exception control by LLVM. In the demo page, I got : declare i8* @llvm.eh.exception() nounwind But, when a try to emit the code by llvm engine, the name is generate with the sufix .132 ( llvm.eh.exception.132 ) and the Function::getIntrinsicID abort the program. It was so : Intrinsic::getDeclaration(llvm_module,Intrinsic::memset,&Tys,1); Now, it's

Hello all, Using the Apache Wiki [1] I summed up what can be used simultaneously by gcc, MSVC and clang. I mostly considered only the latest versions of the proposals where there were several, where not there is a link to a note at the bottom. Furthermore I did not scourge through 3 bug databases and I implicitly trusted the wiki page. I drew up a list of profiles, listing the base

Hi, I have a problem using structs, when calling a function written in C from a LLVM function or calling a LLVM function from a C one. I noticed that the LLVM align double with 4 bytes and our run time routines use 8, in MS Windows. If a use #pragma pack(4) in my C programs, the routines run fine, but I must ensure that all external call should use the #pragma directive. If I change the llvm

Hi, When I try to use va_start(ptr), I got the following problem : Type *Tys = PointerType::get(IntegerType::get(8), 0); return Intrinsic::getDeclaration(llvm_module,Intrinsic::vastart,&Tys,1); ............... The Name generated is "llvm.va_start.p0i8", so, it's not found, abending the process. and Len = 18 In intrinsics.gen : if (Len == 13 && !memcmp(Name,

Abramo, it must be the query for llvmdev, not for cfe-dev. 2011/7/28 Abramo Bagnara <abramo.bagnara at gmail.com>: > ../llvm-r136065/configure --host=i586-mingw32msvc > --enable-targets=host-only --disable-jit --enable-bindings=none > --enable-shared --disable-threads --disable-pthreads > --disable-assertions --disable-optimized I added --enable-shared for cygming a year ago.
