similar to: [LLVMdev] LLVM assembly without basic block

Thank you for reminding me the notion of the basic block. Of course, I know all the assembly takes the form of BBs and is divided into units of BB. OK. It looks better for me to explain what I wanted to do more clear from the first. Actually, I am working on emitting out an assembly of VM by using LLVM. LLVM assembly looks similar with this VM assembly except BB. The VM assembly does not have the

Hi, While playing around on the LLVM, I tried this code: int sum(int n) { if (n == 0) return 0; else return n + sum(n-1); } and this is what "llvm-gcc -O2" gave me: define i32 @sum(i32 %n) nounwind { entry: %tmp215 = icmp eq i32 %n, 0 ; <i1> [#uses=1] br i1 %tmp215, label %bb10, label %tailrecurse.bb10_crit_edge tailrecurse.bb10_crit_edge: ; preds =

The release branch has been created and the llvm-gcc mirror updated (thanks Bill!). I will be doing some preliminary testing before I request the help of the community to test the release. During this time, I ask that developers only commit documentation changes to the release branch and email the list with any bug fixes that need to be merged into the release branch. Bug fixes have to be

Hello, I've come across another example: I'm compiling with clang -S -emit-llvm -std=gnu99 -O3 clang version 2.9 (trunk 118238) Target: x86_64-unknown-linux-gnu Thread model: posix I take the code: int loops(int x) { int ret = 0; for(int i = 0; i < x; i++) { for(int j = 0; j < x; j++) { ret += 1; } } return ret; } and the

I tested a simple function shown as follows for for llvm-g++: ------------------------------------------------------------- void f_loop(long* c, long sz) { long i; for (i = 0; i < sz; i++) { long offset = i * sz; long* out = c + offset; out[i] = 0; } } ------------------------------------------------------------- LLVM assembly was emitted out as follows:

Hi, I'm using LLVM 2.7 right now, and I found "opt -std-compile-opts" has missed some opportunities for optimization: define void @spa.main() readonly { entry: %tmp = load i32* @dst-ip ; <i32> [#uses=3] %tmp1 = and i32 %tmp, -16777216 ; <i32> [#uses=1] %tmp2 = icmp eq i32 %tmp1, 167772160 ; <i1> [#uses=2]

Hello All, What version of g++ is usable to compile the latest LLVM CVS snapshot on a Linux/x86-64 (AMD64) Debian/ Sid or Etch plateform? What compiler do LLVM dzevelopers use to compile LLVM on Linux/X86-64 systems? IKt seems that most versions of g++ fail to compile LLVM and that some others compile it wrongly (producing buggy code)? Why can't g++-4.1 be used? FWIW, the latest gcc

Thank you for this reply. If so, is there any way to merge basic blocks into a single one? Thanks, Seung J.

The bitcode reader will read from any MemoryBuffer object. There are a variety of static methods on MemoryBuffer to create them from files, stdio, and memory. If your buffer is in memory, just create a memorybuffer

I'm attempting to modify a parser generator to emit LLVM code instead of C. So far the experience has been trivial, but I am now running into an error regarding labels that I can't seem to solve. Situation 1: A label is used immediately after a void function call (l6 in this case): <snip> %tmp26 = load i32* @yybegin, align 4 %tmp27 = load i32* @yyend, align 4 call void

Please look here: http://llvm.org/docs/GettingStarted.html#brokengcc I'd suggest late versions of GCC 4.0.x. The 4.1 series has had numerous problems compiling LLVM on x86-64, though some people have

Hello, with the latest LLVM (almost 2.0 CVS) what is the right way to read a module from a byte array fetched from a database? I thought that I could subclass llbm::module to add my own fields (typically, a MySQL id number) and then parse it as bitcode, but I am stuck, since apparently the only way to parse bitcode is to use a BitcodeReader then calling materializeModule gives a fresh llvm

Hello All Does any know about some opensource multithread-compatible (or concurrent) garbage collector library, if possible suitable for LLVM? (I mean that I want several mutator threads; the collector can be stoptheworld or concurrent ....) H.Boehm's conservative GC is multithread compatible, but seems quite slow (allocation is about the time of a C malloc). And it is well known that

Hello All, On a Debian/AMD64 host I am surprised that there is apparently no way to generate position independent code in shared object (i.e. to output files which are easy dlopen-able without pain)? I probably missed something obvious, but what? I want to compile LLVM assembly source code -suitably generated- into .so as directly as possible... Regards -- Basile STARYNKEVITCH

Dear All, I downloaded the latest CVS of llvm I want to try to use LLVM only for JIT only use (generating code in memory for x86 and, when available PowerPC [32bits]) How do I ./configure to avoid being asked about llvmgcc, which, in my very partial understanding, is only used to parse C code... If I understand correctly what Chris Lattner emailed me, LLVM uses only GCC frontend for C & C++

Hello (my machine is a Debian/Sid/x86-64/Core2) Assuming I have one C source file chello.c, to compile it into a dynamically loadable thru dlopen shared object, I can run gcc -fPIC -shared -O chello.c -o chello.so I thought that, assuming I have one llvm source ehello.ll, the equivalent would be llvmc2 -opt ehello.ll -o ehello.so but it is not that simple. Any clues ? May I also

Hi, Seems pass scalar-evolution+indvars fail to get the loop trip count of the following case: int foo(int x, int y, int lam[256], int alp[256]) { int i; int z = y; for (i = 255; i >= 0; i--) { z += x; lam[i] = alp[i]; } return z; } The final optimized ll code is : define i32 @foo(i32 %x, i32 %y, i32* %lam, i32* %alp) nounwind { entry: br label %bb bb:
