Hi all,
I had little success installing llvm inside scratchbox for an ARM
build so have been trying to generate assembly code for arm using the
llc utility. However, llc fails to generate code for arm. Output is as
below...
arvind at zeus:~/tools/llvm/del$ llc main.bc -o mainarm -filetype=asm
-march=arm -f
llc: ARMISelDAGToDAG.cpp:73: llvm::SDOperand
LowerCALL(llvm::SDOperand, llvm::SelectionDAG&): Assertion `isVarArg
== false && "VarArg not supported"' failed.
llc[0x85335ac]
[0xffffe420]
[0xffffe410]
/lib/tls/i686/cmov/libc.so.6(gsignal+0x50)[0xb7d5bdf0]
/lib/tls/i686/cmov/libc.so.6(abort+0x101)[0xb7d5d641]
/lib/tls/i686/cmov/libc.so.6(__assert_fail+0xfb)[0xb7d5543b]
llc[0x82aaeed]
Aborted (core dumped)
arvind at zeus:~/tools/llvm/del$
However, i manage to generate code for other architectures like sparc,
ppc, etc.. Is any additional setup required ?
Thanks in advance

HI Arvind, I think you are using an old llc version. VarArg support was implemented a long time ago.

Hi Sorry for the late reply.. I managed to build the latest release of llvm. Now I get the following error when I try creating the bitcode file: llvm-gcc: --emit-llvm is not supported in this configuration. The configure options were : /home/arvind/llvm/llvm-gcc4.2-2.1.source/configure --prefix=/opt/llvm/ --enable-threads --disable-nls --disable-shared --enable-languages=c --enable-sjlj-exceptions --program-prefix=llvm- On Jan 28, 2008 8:18 PM, Lauro Ramos Venancio <lauro.venancio at gmail.com> wrote:> HI Arvind, > > I think you are using an old llc version.
