Subject: [PATCH 030/144] mode-switching: Add note problem
|
|
|
|
Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=3cd3a09b3f91a1d023cb180763d40598d6bb274b

|
|
optimize_mode_switching uses REG_DEAD notes to track register
|
|
liveness, but it failed to tell DF to calculate up-to-date notes.
|
|
|
|
Noticed by inspection. I don't have a testcase that fails
|
|
because of this.

gcc/
|
|
* mode-switching.cc (optimize_mode_switching): Call
|
|
df_note_add_problem.
