[LLVMdev] Help with error in pass
Dear LLVM guys,
I've solved my problem with the passes, and compiled my first code
using the new register allocator! Debugging was quite easy, using gdb.
The problem was that I was forgetting to initialize the array that records
the physical registers ever used (MachineFunction::UsedPhysRegs). This is
a very minor thing, but I would suggest asserting that the vector has
been initialized

Is it possible to get llvm to generate native machine code
without using gcc and friends ? Do I use lli ?
I'd like to directly create executable code that i can
stick in memory somewhere and jump into (call).
(I'm looking to use llvm in a BSD licensed project).
Simon.

[LLVMdev] LLC fail without gccld optimization on spec2000 int benchmarks
Hi,
In my experiments, I need to disable several linking optimizations. However,
bzip2, vortex and eon failed if "-disable-opt" was passed to gccld. I tried
the out-of-box llvm and the building process provided by llvm-test. The same
problem was observed, when I specified EXTRA_LINKTIME_OPT_FLAGS =
-disable-opt on Makefile.program and simplied typed "make" under

Hmm, this is a little strange. Your LLVM build is non-debug (there's no
line numbers or arguments in any of the llvm related calls). However,
your llvm-gcc build seems to have

[LLVMdev] Problems building cfrontend 4 source on SUSE 10.1
This is an libpath problem. When xgcc runs it wants to dynamically link
the libgcc.so. When you run it from the command line it will find your
system libgcc.so (which works) and so you don't see the segfault. When
you run xgcc from the Makefile, it will have set LD_LIBRARY_PATH to get
your <cfebuilddir>/gcc directory which will find the libgcc.so that it
just built, which is the one

[LLVMdev] llvm-g++: Internal error
Hi,
i used CVS to checkout the source of llvm and llvm-gcc, compiled and built
them on my machine successfully.
i tried a c-language hello program, it was OK.
But when i tried a c++-language hello program, i got:

[LLVMdev] Making a pass available to llc?
Attached is my patch that adds a (debug build only) verifier pass and
support for creating passes specified on the command line to llc.
Let me know if it needs changes to be acceptable. One thing I noticed
is that (eg.) opt and analyze have their options and globals in an
anonymous namespace while llc doesn't. I just used llc's convention -
which is preferable?
As to testing - It works

[LLVMdev] Folding instructions
Dear LLVMers,
I am trying to fold memory operands in the way that is done in
RegAllocLocal.cpp, or in LiveIntervalAnalysis.cpp, but I am getting errors
that
I don't know how to fix. Could someone tell me which steps should I take
in order
to correctly fold memory operands? The code that I am using is:

[LLVMdev] Memory leaks in LLVM
Hi,
Probably some of the leaks Valgrind reports are spurious, but the numbers
seem to be significant enough to demand some attention:

[LLVMdev] failed assertion in PPCJITInfo.cpp when calling native function
Hi,
I am trying to generate LLVM code that calls a "native" function in the parent
program (the program hosting the JIT). I think that I have figured out how to
do this, but I get the following assertion failure when the LLVM code is
executed:
../llvm/lib/Target/PowerPC/PPCJITInfo.cpp:206: failed assertion
