Hi Jeff,
This patch caused a regression on Arm and AArch64 in:
PASS->FAIL: gcc.c-torture/execute/memcpy-2.c execution, -O3
-fomit-frame-pointer
From what I can see, the only place the behaviour of the threader has
changed is in this hunk:
Yes. The old code was dropping the tail off the thread path; if we're
seeing failures on the ARM port as a result of fixing that goof we
obviously need to address them.
Let me take a looksie :-)
If you could pass along a .i file it'd be helpful in case I want to look
at something under the debugger.
