Hi Ahmad, Yes, merging works good. However, my problem is like this - I have a C library which consists of 1000's of functions spread through various files. The functions do not have dependency amoung each other. I want to link only relavant files( files which have functions called from my application). Since ar has a global symbol table, I believe it should be faster to look for a symol in

Hi Ankur, Why do you need archive in this case? The other way of doing this is to merge all bitcode files into single file: $ clang -c -emit-llvm abc.c -o abc.bc $ clang -c -emit-llvm bcd.c -o bcd.bc llvm-link bcd.bc abc.bc -o merged.bc Cheers, Ahmad From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of ankur deshwal Sent: 21 February 2013 17:54 To:

Hi, I get this error: ------------------ Reader.cpp:464: error: `intptr_t' undeclared (first use this function) ------------------ It doesn't seem that you include <stddef.h>, where the intptr_t is declared, in the source file. When I included the header, it compiled without errors. The same error seems to be present for ReaderWrappers.cpp. /Henrik

Hi Ankur, Since you use -Xclang, the clang executable passes multiple triples to "clang -cc1". You can see that if you add the -v option. I'm sure there is someone here who can explain it better than I... Anyhow, I think you better use clang -cc1. Make sure -cc1 is the first command line option you use. $ clang -cc1 -fno-builtin -emit-llvm-bc -triple spir-unknown-unknown

Hi Guy, Thanks a lot for the clarification. I tried using the triple for SPIR as $ clang -x cl -fno-builtin -emit-llvm -c -Xclang -triple -Xclang spir-unknown-unknown Simple_Kernel.cl However I get the following error. error: unknown target triple 'spir-unknown-unknown', please use -triple or -arch I also tried with triple nvptx-unknown-unknown clang -x cl -fno-builtin -emit-llvm -S

Hi Ankur, For a MachineBasicBlock you can call getBasicBlock() to find the IR level BasicBlock from which it was generated (if there isn't a one, it will return NULL). I don't know of a way to get a finer granularity than that, though. -Jim On Jul 1, 2011, at 1:06 AM, ankur deshwal wrote: > Hi, > > Is there any way to get a pointer to the LLVM Instr from which a >

Hello everyone, Thanks a lot for the help. -target nvptx worked great with llvm-3.2. However it gives error with -target spir. LLVM/Clang trunk although works good for both options ( probably because spir is still work in progress ).

The videos are OK now. Except the video of "Autovectorization with LLVM" that have a little mistake with "_" and "-" in the filenames.

I guess I miss-interpreted the text in [2]. It talks about the optimizations are hindered if the compiler driver invokes link time optimizer "separately". I found that all files compiled are in bc format. Also in library archives, the embedded files were in bitcode format. So the gold linker and LLVMgold plugin are indeed working fine. However, there is still question over only 6% gain

This make sure there is no mismatch between the size of the integer value that Int64_val returns, and the size of the guestfs_h pointer. This should fix the warning on 32bit environments (and thus build, when --enable-werror is enabled). --- mllib/visit-c.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mllib/visit-c.c b/mllib/visit-c.c index b46dd33..b1c1216 100644 ---

I have written a new pass, it compiles ok but crashes when i run it with error (llvm::Pass::Pass(llvm::PassKind, intptr_t): Assertion `pid && "pid cannot be 0"' failed.).

Hi, I was trying to use the following code in a if condition I->getOperand(0)->hasName() where I is an instruction with following condition already true - I->getOpcode() == Instruction::Call When I compiled a C code with llvm-2.9, I see a function call with no operand name (for operand 0) . This happens for a function with varArgs. The interesting part is that the same C code when

Hi, Is there any way to get a pointer to the LLVM Instr from which a particular MachineInstr is generated ? Although I understand it goes through many optimization after a LLVM instruction is converted to SDAG node, so maintaining such a mapping will be hard. Still is the mapping stored some where which can give some sane results at least in case of -O0? Thanks and regards, Ankur

Hi Jordan, You're right, and the driver -target option works perfectly with the SPIR triples.
