Hi,
Today I managed to link ioquake3, but generating a binary does not
work yet.
1) On OSX, I get:
Error: Code generator does not support intrinsic function
'llvm.ppc.altivec.lvsl'!
when I do: llc file.bc -march=c -o file.c
2) On Linux X86, llc does not give any problem, but I get this while
compiling the generated .c file:
error: unknown register name 'S' in 'asm'
This is the offending line (notice the "S" on the last line):
__asm__ volatile ("\tpushal\t\t\t\t\n\tmovl %0,%%esi\t\t\n\tmovl %
1,%%edi\t\t\n\tcall *%2\t\t\t\n\tmovl %%esi,%0\t\t\n\tmo\
vl %%edi,%1\t\t\n\tpopal\t\t\t\t\n"
:"=m"(memProgramStack_2E_5872),"=m"(memOpStack_2E_5873)
:"m"(memEntryPoint_2E_5874),"m"(memProgramStack_2E_5872),"m"(me
mOpStack_2E_5873)
:"D","S");
Apparently, leaving out "S" helps (compiling the .c file works), but
what does it do and why is it here?
3) Regarding bug 1446 (http://llvm.org/bugs/show_bug.cgi?id=1446):
the proposed patch for the file called sv_client.c indeed works on
OSX, but on Linux X86 -O3 it still does not work. More in particular,
the frontend is now stuck inside the for-loop on lines 176-->391 of
PromoteMemoryToRegister.cpp when in the control flow of -scalarrepl:

I was poking around, but I didn't spot a PayPal link for the t-shirts and/or supporting LLVM. Any follow-up from the pre-meeting discussions? -Gabe

Thanks!Has happened: http://llvm.org/bugs/show_bug.cgi?id=1482.> Very strange. Is everything up to date?Yes, I applied your patch but it still hangs on -O3, not on -O0 (http://llvm.org/bugs/show_bug.cgi?id=1446). Kind regards, Bram Adams GH-SEL, INTEC, Ghent University (Belgium)
