Investigation of g77.f-torture/execute/short.f -Os failure
- To: "'gcc-bugs at gcc dot gnu dot org'" <gcc-bugs at gcc dot gnu dot org>

Test g77.f-torture/execute/short.f -Os execution is the only g77 testsuite
failure on mips-sgi-irix6.5. It also fails on i?86-pc-gnu-linux. This is a
partial analysis of the failure.
Tracking back though the gcc-testresults archive I see:
mips-sgi-irix6.5 - David Billinghurst
20000313 pass
20000320 fail
mips-sgi-irix6.2 - Kaveh Ghazi
20000313 pass
20000314 fail
i686-pc-gnu-linu - Kaveh Ghazi
20000313 pass
20000314 fail - with many other g77 failures
...
20000317 ditto
20000318 still fails, but most of the other failures gone
so it looks like a change on or about 20000313 caused the failure. The are
no g77 ChangeLog entries around that time.
The test case can be further simplified (below) and compiling the two
routines seperately shows the error is in the function f. I then generated
all the debug output from "g77 -c -Os -da f.f". The error is obvious in
sub.f.17.sched, where reg 100 and reg 102 are used, but not set. Previously
they held the constants 0.5 and -2.0 respectively. Now everything looks OK
in sub.f.08.gcse, but I have my doubts about sub.f.09.loop. Any ideas?
