From: Kyrylo Tkachov <[email protected]>
cond_exec_process_insns and cond_exec_process_if_block document their
parameters with K&R-style comments interleaved between them, where each
comment trails the parameter it describes and so reads as if it belonged to
the next one. Move the descriptions into the function comment, which is what
the rest of the file does. Comment-only.
gcc/ChangeLog:
* ifcvt.cc (cond_exec_process_insns): Document the parameters in the
function comment instead of between them.
(cond_exec_process_if_block): Likewise.
