[LLVMdev] problems with dwarf/gdb

[Ken McMillan]

Well...

$ ~/software/llvm-gcc4.2-2.5-x86-linux-RHEL4/bin/llvm-gcc -g gdb1.c -o gdb1
/tmp/ccbAj8x9.s: Assembler messages:
/tmp/ccbAj8x9.s:35: Error: suffix or operands invalid for `push'
/tmp/ccbAj8x9.s:44: Error: suffix or operands invalid for `pop'
/tmp/ccbAj8x9.s:56: Error: suffix or operands invalid for `push'
/tmp/ccbAj8x9.s:65: Error: suffix or operands invalid for `pop'
/tmp/ccbAj8x9.s:77: Error: suffix or operands invalid for `push'
/tmp/ccbAj8x9.s:94: Error: suffix or operands invalid for `pop'

Don't know what that's about. If I use the -S option and then
compile the .s file with gcc, it works fine (but again, can't set
breakpoints in gdb).

I am currently using gdb 6.6. Will try 6.8...

Thanks -- Ken
