Hi All,
This updates the build system to split up match.pd files into chunks of 10.
This also introduces a new flag --with-matchpd-partitions which can be used to
change the number of partitions.
For the analysis of why 10 please look at the previous patch in the series.
Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
Ok for master?
Thanks,
Tamar
gcc/ChangeLog:
PR bootstrap/84402
* Makefile.in (NUM_MATCH_SPLITS, MATCH_SPLITS_SEQ,
GIMPLE_MATCH_PD_SEQ_SRC, GIMPLE_MATCH_PD_SEQ_O,
GENERIC_MATCH_PD_SEQ_SRC, GENERIC_MATCH_PD_SEQ_O): New.
(OBJS, MOSTLYCLEANFILES, .PRECIOUS): Use them.
(s-match): Split into s-generic-match and s-gimple-match.
* configure.ac (with-matchpd-partitions,
DEFAULT_MATCHPD_PARTITIONS): New.
* configure: Regenerate.
