[LLVMdev] Generate .debug_info for asm files?

[Alex]

Dear LLVM devs,

I've noticed that LLVM's assembler (and hence clang) doesn't generate debug
data when assembling, even when run with "-g".

Users can add their own CFI/line number data with assembler directives. But
GDB ignores the line number data if you don't have a DIE in the .debug_info
section which identifies the compilation unit. (I'm not an expert on GDB,
but this is the conclusion I have drawn from single-stepping through GDB on
some test binaries.)

Would you be interested in a patch which makes the assembler generate
.debug_info?

Thanks,
Alex Dowad
