2020-05-15c++: Enable coroutines with -std=c++20.Jason Merrill5-12/+17
Now that GCC 10 is out it seems time. People can still choose to disable coroutines with -fno-coroutines. This also switches the coroutines testsuite to run in C++20 mode.

2020-05-15contrib: Handle GDB specific test result typesAndrew Burgess3-3/+20
This commit is for the benefit of GDB, but as the binutils-gdb repository shares the contrib/ directory with gcc, this commit must first be applied to gcc then copied back to binutils-gdb. This commit extends the two scripts contrib/dg-extract-results.{py,sh} to handle some new, GDB specific test result types. These test results types should never appear in GCC, or any other tool that shares the contrib/ directly, so this change should be harmless. In this patch series: https://sourceware.org/pipermail/gdb-patches/2020-April/167847.html changes were made in GDB's use of Dejagnu so that two additional conditions could be detected, these are: 1. Test names that contain either the build or source paths. Such test names make it difficult to compare the results of two test runs of GDB from two different directories, and 2. Duplicate test names. Duplicates make it difficult to track down exactly which test has failed. When running Dejagnu on GDB we can now (sometimes) see two additional test result types matching the above conditions, these are '# of paths in test names' and '# of duplicate test names'. If the test is run in parallel mode (make -j...) then these extra test results will appear in the individual test summary files, but are not merged into the final summary file. Additionally, within the summary file there are now two new types of test summary line, these are 'PATH: ...' and 'DUPLICATE: ...', these allow users to quickly search the test summary to track down where the offending test names are. These lines are similarly not merged into the unified gdb.sum file after a parallel test run. This commit extends the dg-extract-results.* scripts to calculate the totals for the two new result types, and to copy the new test summary lines into the unified summary file. contrib/ChangeLog: * dg-extract-results.py: Handle GDB specific test types. * dg-extract-results.sh: Likewise.

2020-05-15tree-optimization/33315 - common stores during sinkingRichard Biener6-5/+242
This implements commoning of stores to a common successor in a simple ad-hoc way. I've decided to put it into the code sinking pass since, well, it sinks stores. It's still separate since it does not really sink code into less executed places. It's ad-hoc since it does not perform any dataflow or alias analysis but simply only considers trailing stores in a block, iteratively though. If the stores are from different values a PHI node is inserted to merge them. gcc.dg/tree-ssa/split-path-7.c shows that path splitting will eventually undo this very transform, I've decided to not bother with it and simply disable sinking for the particular testcase. Doing this transform is good for code size when the stores are from constants, once we have to insert PHIs the situation becomes less clear but it's a transform we do elsewhere as well (cselim for one), and reversing the transform should be easy. 2020-05-15 Richard Biener <rguenther@suse.de> PR tree-optimization/33315 * tree-ssa-sink.c: Include tree-eh.h.

2020-05-14libiberty: Update D symbol demangling for latest ABI spec.Iain Buclaw3-261/+613
Some small improvements and clarifications have been done in the D ABI specification to remove all ambiguities found in the current grammar, this implementation now more closely resembles the spec, whilst maintaining compatibility with the old ABI. Three new rules have been added to the ABI. 1. Back references using 'Q', analogous to C++ substitutions, compresses repeated identifiers, types, and template symbol and value parameters. 2. Template aliases to externally mangled symbols are prefixed with 'X'. This includes any symbol that isn't extern(D), or has its name overriden with pragma(mangle). This fixes an ambiguity where it was not clear whether 'V' was an encoded calling convention, or the next template value parameter. 3. Alias parameters, templates, and tuple symbols no longer encode the symbol length of its subpart. Tuples are now terminated with 'Z'. This fixes another ambiguity where the first character of the mangled name can be a digit as well, so the demangler had to figure out where to split the two adjacent numbers by trying out each combination. libiberty/ChangeLog: * d-demangle.c (enum dlang_symbol_kinds): Remove enum.

2020-05-14amdgcn: fix vcc clobber in vector load/storeAndrew Stubbs6-51/+217
This switches the code that expands scalar addresses to vectors of addresses from using VCC to using CC_SAVE_REG, for the lo-part to hi-part carry values. These were fine in code expanded in earlier passes, but addresses expanded late, such as for stack spills or reloads, could clobber live VCC values, causing execution failures. This is the first target-specific testcase for GCN, so the new .exp file is included. 2020-05-14 Andrew Stubbs <ams@codesourcery.com> gcc/ * config/gcn/gcn-valu.md (add<mode>3_zext_dup): Change to a define_expand, and rename the original to ...
