Our finalization handling is a mess. Really, we should get to try and get this fixed for gcc 11. In the meantime, here is a patch which fixes a regression I introduced when fixing a regression with a memory leak.

2020-05-26revamp dump and aux output namesAlexandre Oliva1-2/+2
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. gcc/ChangeLog: * common.opt (aux_base_name): Define.

2020-05-20Fortran : ProcPtr function results: 'ppr@' in error message PR39695Mark Eggleston3-4/+20
The value 'ppr@' is set in the name of result symbol, the actual name of the symbol is in the procedure name symbol pointed to by the result symbol's namespace (ns).
