Bug ID: 104006
Summary: [12 regression] power-ieee128 merge breaks Solaris
build
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libfortran
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: jakub at gcc dot gnu.org, tkoenig at gcc dot gnu.org
Target Milestone: ---
Target: *-*-solaris2.11
Between 20220111 and 20220112, Solaris bootstrap (both sparc and x86) got badly
broken, obviously due to the power-ieee128 merge:
* Initially, the build aborted with
make[2]: *** No rule to make target 'gfortran.ver-sun', needed by 'all'. Stop.
This can easily be fixed by renaming the target to gfortran.ver-sun.
* What's way worse, however, is that parallel builds fail repeatedly in
libgfortran:
On x86 (-j48), I get

also for several other files. All those definitions live in the generated
kinds.h. I cannot yet tell if the header isn't generated atomically.
On sparc (-j64), I get instead:
/vol/gcc/src/hg/master/local/libgfortran/ieee/ieee_exceptions.F90:28:2:

Fatal Error: kinds.inc: No such file or directory
I notice that there's no .deps/*.Plo file for this source file; probably
some dependencies are missing.
Manually restarting the libgfortran build (often several times) ultimately
lets the build succeed.
For comparison's sake I also tried -j64 builds on x86_64-pc-linux-gnu and
i686-pc-linux-gnu. Both succeeded without issues.
