xtensa: Fix PR target/78118
It started failing after the following commit:
32e90dc6a0cda45 ("PR
rtl-optimization/61047").
The change that made xtensa backend go ICE looks completely unrelated,
and indeed, the issue is caused by the side effect of
compute_frame_size() function call hidden in the
INITIAL_ELIMINATION_OFFSET macro. This call updates the value of the
xtensa_current_frame_size static variable, used in "return" instruction
predicate. Prior to the change the value of xtensa_current_frame_size was
set to 0 after the end of epilogue generation, which enabled the "return"
instruction for the CALL0 ABI, but after the change the additional
INITIAL_ELIMINATION_OFFSET calls make xtensa_current_frame_size non-zero
and "return" pattern unavailable.
Get rid of the global xtensa_current_frame_size and
xtensa_callee_save_size variables by moving them into the
machine_function structure. Implement predicate for the "return" pattern
as a function. Don't communicate completion of epilogue generation
through zeroing of xtensa_current_frame_size, add explicit epilogue_done
variable to the machine_function structure. Don't update stack frame
layout after the completion of reload.

runtime: recreate function called by cgo -gccgo
When using cgo -gccgo calls to C.GoString, C.GoStringN, and C.GoBytes
are turned into calls to __go_byte_array_to_string and
__go_string_to_byte_array. Those functions were removed when the string

libgo: only rebuild package if dependent .gox has changed
Use mvifdiff and stamp files to track whether a .gox file has changed.
When package A depends on package B, and we rebuild package B, only
rebuild package A if package B's .gox file changes. This is safe
because when package A imports package B it only reads package B's .gox
file. This means that changes that do not affect export information
will not cause dependent packages to be recompiled.

Le-Chun Wu [Mon, 31 Oct 2016 13:21:59 +0000 (13:21 +0000)]
Add -Wshadow=global -Wshadow=local and -Wshadow=compatible-local.
This patch from Le-Chun Wu adds two new shadow warning flags for
C and C++:
-Wshadow=local which warns if a local variable shadows another local
variable or parameter,
-Wshadow=compatible-local which warns if a local variable shadows
another local variable or parameter whose type is compatible with
that of the shadowing variable.
It is already on the google/main branch (Google ref 39127) and was
previously submitted by Diego Novillo and reviewed on
http://codereview.appspot.com/4452058
I addressed the review comments and made the following changes:
- Add -Wshadow=global (the default alias for -Wshadow).
- Make the documented options -Wshadow=global, -Wshadow=local
and -Wshadow=compatible-local (with hidden undocumented aliases
-Wshadow-local and -Wshadow-compatible-local for compatibility).
- The -Wshadow=global, -Wshadow=local and -Wshadow=compatible-local
relationships are expressed in common.opt instead of in opts.c
and documented in invoke.texi.
- The "previous declaration" warnings were turned into notes and use
the (now) existing infrastructure instead of duplicating the warnings.
The testcases have been adjusted to expect the notes.
- The conditional change in name-lookup.c for non-locals (where we
don't want to change the warnings, but just check the global ones)
has been dropped.
- Use warning_at in c-decl.c (warn_if_shadowing).

compiler: fix slice/array evaluation order bug
There was a phase ordering issue in the handling of "keyed" array
literal expressions: the lowering phase was canonicalizing the
indices/vals before the phase that fixed evaluation order, meaning that
the evaluation order was incorrect. The fix is to capture the orginal
ordering and use that ordering when doing traversals (there is already
something similar being done for struct literal expressions).

combine: Improve change_zero_ext (fixes PR71847)
This improves a few things in change_zero_ext. Firstly, it should use
the passed in pattern in recog_for_combine, not the pattern of the insn
(they are not the same if the whole pattern was replaced). Secondly,
it handled zero_ext of a subreg, but with hard registers we do not get
a subreg, instead the mode of the reg is changed. So this handles that.
Thirdly, after changing a zero_ext to an AND, the resulting RTL may become
non-canonical, like (ior (ashift ..) (and ..)); the AND should be first,
it is commutative. And lastly, zero_extract as a set_dest wasn't handled
at all, but now it is.
This fixes the testcase in PR71847, and improves code generation in some
other edge cases too.
