7 years agoi386: Update INCOMING_FRAME_SP_OFFSET for exception handler
H.J. Lu [Sun, 30 Jul 2017 14:10:32 +0000 (14:10 +0000)]
i386: Update INCOMING_FRAME_SP_OFFSET for exception handler

Since there is an extra error code passed to the exception handler,
INCOMING_FRAME_SP_OFFSET is return address plus error code for the
exception handler.  This patch updates INCOMING_FRAME_SP_OFFSET to
the correct value for the exception handler.

This patch exposed a bug in DWARF stack frame CFI generation, which
assumes that INCOMING_FRAME_SP_OFFSET is the same for all functions:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81570

It sets and caches the incoming stack frame offset with the same
INCOMING_FRAME_SP_OFFSET for all functions.  When there are both
exception handler and normal function in the same input, the wrong
incoming stack frame offset is used for exception handler or normal
function, which leads to

    temporary for each result.  Then the call expression would copy each

[Patch AArch64 Obvious] Unify branch costs to generic_branch_cost

All the cores in AArch64 use the pair {1, 3} for their branch costs. As
that is covered by generic_branch_cost, we can just use that directly and
save the tiny amount of redundant code. If in future any core wants to
modify this, they can always add a special-case branch-cost back.
