Hi,
I want to prefix labels in the assembly output with the current function
name. So
in function foo(), I would like to have labels such as foo_L1 and foo_L12.
This
makes it possible for me to recognize code in the output of profiles. Any
idea
where I can find the name of the current function? I tried
current_function_name() but that does not work when compiling C++.
Jan

Try "(*lang_hooks.decl_printable_name) (cfun->decl, 0)".

Another benefit: this might make it easier for the compile server
to generate identical assembler files when compiling multiple
output files compared to multiple non-server compilations.
An altenative would be to reset the label-counter, but that causes
with inlining. It is possible tree-based inling might reduce the
problem, but "function-relative" label names avoids the problem.
