[LLVMdev] Building llvm-gcc4 on amd64
I am also trying to build llvm-gcc4 and llvm as you are on amd64 linux. I am currently running into the error "Did not get a target machine!" on the first file compiled by xgcc. Did you encounter this error at all? Also, what distribution did you use? GCC version, and target triple? Thanks, -Chandler Carruth On 12/10/06, Domagoj Babic <babic.domagoj at gmail.com> wrote: >

[LLVMdev] How to compile apps to bc files with the new llvm-gcc4?
Hi, I'm trying to compile some apps with the new llvm-gcc4 on amd64 linux to .bc files, rather than to the native code. The same process I used to build those apps before with llvm-gcc3 doesn't work: 1) export CC=llvm-gcc CXX=llvm-g++ CFLAGS="-g -fno-inline" CXXFLAGS="-g -fno-inline" 2) cd <whatever-app>; ./configure 3) make CFLAGS+=-emit-llvm

[LLVMdev] How to compile apps to bc files with the new llvm-gcc4?
Unless I'm missing something, the problem lies directly with the fact that you are trying to do a link-stage operation with the GCC frontend. GCC, by default, probably runs "ld" or another system linker, which grabs the executable from binutils. This linker hasn't been modified (yet) to include support for .bc files, but you're compiler is emitting byte code to the *.o files.

[LLVMdev] New automated decision procedure for path-sensitive analysis
Dear LLVMers, This email is intended for those interested in path-sensitive analysis, integer overflow analysis, static analysis, and (perhaps) loop invariant computation. Traditionally, such analyses have been considered too expensive to be practical, and were mostly an academic curiosity. The core of the problem is the lack of adequate automated decision procedures which could quickly

[LLVMdev] SCCP and undef branches
Hi, Here's something I don't understand... How come that UNDEF can appear as a branch condition at all? I just can't think of any ways. If you write something like fun() { int x; if (x > 100) { ... } else { ... } } LLVM generates a boolean temporary that compares (uninitialized) value of x with 100. Second, if it already can appear, isn't that a bug that

[LLVMdev] struct as a function argument
Hi everybody! I recently started using llvm in a project on inferring additional information about pointers based on their types, casts, etc. The following simple example is giving me a headache :): typedef struct { int a; short b, c; int d, e, f; } foo; void bar(foo f) { short s; s = f.b; } int main(void) { foo p; bar(p); } Because llvm doesn't allow structures and arrays

[LLVMdev] LLVM Conference 2007 ?
LLVMers, The LLVM Oversight group is trying to assess whether there is sufficient interest in the LLVM development community for holding an LLVM Conference next summer. If getting together with your fellow LLVM Developers sounds interesting to you, please respond to me (off list) and I'll summarize the results. Here's our current thinking: * Venue: West Coast, USA. Probably either San

[LLVMdev] FunctionPass requiring SCCs
I have a FunctionPass F that needs a list of all the SCCs for use in its doFinalization() method. Let's say I write a CallGraphSCCPass C that creates an array of all SCCs. Let C be required by F, and let F call getAnalysis<C>() from its doFinalization() method. Am I guaranteed that C's runOnSCC() method will have executed on all SCCs before F's doFinalization() method?

[LLVMdev] Recharging the batteries
Hi, I've noticed that http://llvm.org/status/ hasn't been updated for a while, so I tought that some of you might find the following information interesting and/or encouraging... For benchmarking the stuff I'm working on I needed to compile a number of open-source packages. The settings I used: AS=llvm-as lLD=llvm-ld AR=llvm-ar CXX=llvm-g++ CC=llvm-gcc CFLAGS="-g
