New Revision: 44803
URL: http://llvm.org/viewvc/llvm-project?rev=44803&view=rev
Log:
Disable cfi directives for now, darwin does't support them.
These should probably be something like:
CFI(".cfi_def_cfa_offset 16\n")
where CFI is defined to a noop on darwin and other platforms
that don't support those directives.
