[LLVMdev] opt, llcc, ll++, -O1, -O2, -O3
Hi devels,
there are two issues concerning invoking
optimizations:
1.
this document:
http://llvm.cs.uiuc.edu/docs/GettingStarted.html
is very nice, it would be good though to add in a section
An Example Using the LLVM Tool Chain
examples on optimization step.
2.
If i am not wrong there is no tool, which integrates all
steps:
llvmgcc->opt->llc into something like llcc
(and

Yup, this is EXACTLY what is going on.

Yes, it's purely static

BTW, Chris, what should be then an analogy
of "gcc -O3 -S foo.c" in LLVM framework?
The invocation of
$ llvmgcc -S ackerman.c -o ackerman -Wl,-native-cbe
does not produce native assebler output as one might expect.

[LLVMdev] Compiling FreeType 2.1.9 with LLVM 1.4
Adam,
I recant my previous message. I built FreeType with GCC not LLVMGCC by
accident (I shoulda checked!). The thing is, FreeType's makefiles don't
respect environment variables. So, I did this:
CC=/path/to/llvmgcc CXX=/path/to/llvmg++ configure
make
and was able to reproduce the problem. Not sure what's up with that but
as Misha pointed out, llvmgcc isn't any

[LLVMdev] Question about insert function or instruction.
Hi llvmer,
I am trying to learn how to use llvm. My question is
described as the following,
there has already a testcase code, and I get bytecode
by using llvmgcc. What I want to do is to insert a
call funcation into each basic block, which is for
statistic some information.
1) I implement call function in another c/cpp file and
can I insert the external call function to existed
bytecode ? if it

[LLVMdev] Status of the 2.3 release - volunteers needed.
Many of you are probably wondering about the status of the 2.3
release. Unfortunately, this release has been very difficult and the
list of regressions very high. The list has finally dwindled down to
the following regressions:
Linux/x86:
SingleSource/Benchmarks/CoyoteBench/fftbench [ JIT Codegen, JIT]
MultiSource/Applications/minisat/minisat [CBE]
Darwin/x86:

I will test on Darwin/PPC, I'll try the precompiled llvmgcc, objdir !=
srcdir.

[LLVMdev] Starting with LLVM-GCC on Cygwin
Hi,
I would like to use LLVM-GCC to compare its performance with other compilers.
Something like testsuite "Computing very large Fibonacci numbers" at
http://article.gmane.org/gmane.comp.lang.c%2B%2B.perfometer/37.
My environment:

Windows 2000
Cygwin
$ uname -srom
CYGWIN_NT-5.0 1.5.11(0.116/4/2) i686 Cygwin
