Bug ID: 83408
Summary: microblaze: long compile times
Product: gcc
Version: 7.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: arnd at linaro dot org
Target Milestone: ---

Building an 'allmodconfig' linux kernel for microblaze gets stuck in a couple
of files that take several hours to compile on a fast machine. 'perf'
shows the time is spent mostly in two functions:
88.17% cc1 cc1 [.] find_base_term
9.47% cc1 cc1 [.]
cselib_sp_based_value_p
...
reproduce with "microblaze-linux-gcc-7.2.1 -O2 -c enic_main.i". An older
compiler version I happened to have (gcc-4.9.3) behaves similarly. I did not
wait for the compilation to finish but saw in older build reports that it
eventually continued or crashed.
