After the patch that revamped dump and aux outputs, GCC compilation
drivers built without Ada would reject -d* options. Such options
would only be validated because of the %{d*} in Ada lang specs, though
other languages had it as well. Other languages had %< specs that had
to be there before %{d*} %:dumps(), while Ada was missing them.
Adding them to Ada brought the same problem to compilers that had Ada
enabled.
The reason validation failed was that they mishandled %< specs,
advancing past the beginning of the next spec, causing it not to be
handled. Since %{d*} appeared after an odd %<, it was thus ignored.
The logic of validate_switches originally skipped the closing brace
that matched the opening brace, but this shouldn't happen for %<.
Fixed by letting validate_switches know whether it is handling a
braced group or a single atom, and behaving accordingly.
gcc/ChangeLog:
* gcc.c (validate_switches): Add braced parameter. Adjust all
callers. Expected and skip trailing brace only if braced.
Return after handling one atom otherwise.
(DUMPS_OPTIONS): New.
(cpp_debug_options): Define in terms of it.
gcc/ada/ChangeLog:
* gcc-interface/lang-specs.h (ADA_DUMPS_OPTIONS): Define in
terms of DUMPS_OPTIONS. Replace occurrences of %{d*} %:dumps
with it.

This patch simplifies (!!!) the logic governing the naming of dump
files and auxiliary output files in the driver, in the compiler, and
in the LTO wrapper. No changes are made to the naming of primary
outputs, there are often ways to restore past behavior, and a number
of inconsistencies are fixed. Some internal options are removed
(-auxbase and -auxbase-strip), sensible existing uses of -dumpdir and
-dumpbase options remain unchanged, additional useful cases are added,
making for what is still admittedly quite complex. Extensive
documentation and testcases provide numerous examples, from normal to
corner cases.
The most visible changes are:
- aux and dump files now always go in the same directory, that
defaults to the directory of the primary output, but that can be
overridden with -dumpdir, -save-temps=*, or, preserving past behavior,
with a -dumpbase with a directory component.
- driver and compiler now have the same notion of naming of auxiliary
outputs, e.g. .dwo files will no longer be in one location while the
debug info suggests they are elsewhere, and -save-temps and .dwo
auxiliary outputs now go in the same location as .su, .ci and
coverage data, with consistent naming.
- explicitly-specified primary output names guide not only the
location of aux and dump outputs: the output base name is also used in
their base name, as a prefix when also linking (e.g. foo.c bar.c -o
foobar creates foobar-foo.dwo and foobar-bar.dwo with -gsplit-dwarf),
or as the base name instead of the input name (foo.c -c -o whatever.o
creates whatever.su rather than foo.su with -fstack-usage). The
preference for the input file base name, quite useful for our
testsuite, can be restored with -dumpbase "". When compiling and
linking tests in the testsuite with additional inputs, we now use this
flag. Files named in dejagnu board ldflags, libs, and ldscripts are
now quoted in the gcc testsuite with -Wl, so that they are not counted
as additional inputs by the compiler driver.
- naming a -dumpbase when compiling multiple sources used to cause
dumps from later compiles to overwrite those of earlier ones; it is
now used as a prefix when compiling multiple sources, like an
executable name above.
- the dumpbase, explicitly specified or computed from output or input
names, now also governs the naming of aux outputs; since aux outputs
usually replaced the suffix from the input name, while dump outputs
append their own additional suffixes, a -dumpbase-ext option is
introduced to enable a chosen suffix to be dropped from dumpbase to
form aux output names.
- LTO dump and aux outputs were quite a mess, sometimes leaking
temporary output names into -save-temps output names, sometimes
conversely generating desirable aux outputs in temporary locations.
They now obey the same logic of compiler aux and dump outputs, landing
in the expected location and taking the linker output name or an
explicit dumpbase overrider into account.
- Naming of -fdump-final-insns outputs now follows the dump file
naming logic for the .gkd files, and the .gk dump files generated in
the second -fcompare-debug compilation get the .gk inserted before the
suffix that -dumpbase-ext drops in aux outputs.
