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. The
change to coro.h is only necessary for co-await-11-forwarding.C; we could
alternatively #include <utility> just in that file.

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.

* dg-extract-results.py: Handle GDB specific test types.
* dg-extract-results.sh: Likewise.

PFACC/PFNACC 3dNow! instructions got their corresponding SSE alternative
in SSE3, so these can't be implemented with TARGET_MMX_WITH_SSE, which
implies SSE2. These instructions are only generated via builtins, and
since several 3dNow! insns have no corresponding SSE alternative,
we can't avoid MMX registers with 3dNow! builtins anyway.
Add SSE3/AVX alternatives to the insn pattern, so compiler will be able
to use XMM registers when available, but don't prevent MMX registers,
since they are needed when SSE3 is not active.

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.

It is no longer needed as we are running rvrp[12] and verifying usage

This keeps the indentation from going haywire when GORI dumping
is turned on and off during a compilation unit.

Move all the classes and support routines that are not meant to
be upstreamed, into their own files.
Also, add the initial cut of the classes needed to compare and
trap when IL changes are noticed in evrp. This is disabled for now.
|
|
This conversion has nothing to do with ranges, and the way it uses global
ranges versus local ranges is interfering with our ability to diagnose
differences between evrp and rvrp1.
|
|
Since the ranger is on-demand, dumping the known range for each SSA use
causes us to calculate the ranges ahead of time, and confuse the listing.
For now, turn it off, so the range calculation isn't displayed.
|
|
This gives better ranges for the simplifier class since it's using the
context in which the statement appears.

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.

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.
