2016-10-31Add -Wshadow=global -Wshadow=local and -Wshadow=compatible-local.Le-Chun Wu15-11/+439
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). gcc/ChangeLog: 2016-10-30 Le-Chun Wu <lcwu@google.com> Mark Wielaard <mjw@redhat.com> * doc/invoke.texi: Document Wshadow-local and Wshadow-compatible-local. * common.opt (Wshadow=global): New option.

2016-10-30compiler: fix slice/array evaluation order bugIan Lance Taylor3-105/+147
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).

2016-10-28compiler, runtime: copy slice code from Go 1.7 runtimeIan Lance Taylor14-472/+661
Change the compiler handle append as the gc compiler does: call a function to grow the slice, but otherwise assign the new elements directly to the final slice. For the current gccgo memory allocator the slice code has to call runtime_newarray, not mallocgc directly, so that the allocator sets the TypeInfo_Array bit in the type pointer. Rename the static function cnew to runtime_docnew, so that the stack trace ignores it when ignoring runtime functions. This was needed to fix the runtime/pprof tests on 386.

2016-10-28combine: Improve change_zero_ext (fixes PR71847)Segher Boessenkool2-4/+60
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. PR target/71847 * combine.c (change_zero_ext): Handle zero_ext of hard registers. Swap commutative operands in new RTL if needed. Handle zero_ext in the set_dest.

2016-10-28S/390: Add static OSC breaker if necessary.Andreas Krebbel5-0/+197
This patch adds a magic OSC (operand store compare) break instruction which is necessary if a store is followed closely by a load with same base+indx+displ while either base or index get modified in between.

2016-10-28S/390: Add support for arch<n> arch/tune options.Andreas Krebbel8-10/+430
This patch adds an alternate CPU level naming following the architecture level number in the Principles of Operations manual. So instead of having z196, zEC12, and z13 you can use arch9, arch10, and arch11. The old cpu names stay valid and should preferably be used. The alternate names are supposed to improve compatibility with the IBM XL compiler toolchain which uses the arch numbering. gcc/testsuite/ChangeLog: 2016-10-28 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * gcc.target/s390/target-attribute/tattr-m64-33.c: New test. gcc/ChangeLog: 2016-10-28 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/s390/s390.opt: Support alternate cpu level naming (archXX). * config.gcc: Support alternate archXX cpu levels with --with-arch= and --with-tune=. * config/s390/linux.h: Translate new archXX cpu levels to the original names when calling GAS. * config/s390/tpf.h: Likewise. * doc/invoke.texi: Document the alternate cpu level names.
