Subject: bug#51104: comp-tests.elc messes up after reconfiguring for different machine
Date: Fri, 8 Oct 2021 15:59:06 -0700 [thread overview]
Message-ID: <c0c953fa-71e1-549c-c3ed-b88323f421b7@cs.ucla.edu> (raw)
When trying out the emacs-28 branch on both 32- and 64-bit platforms, I
had test failures that I tracked down to this line:
test/src/comp-tests.el:933: (integer ,most-negative-fixnum
,most-positive-fixnum))
My problem was that I'd built test/src/comp-tests.elc on a 32-bit
platform (using "./configure CC='gcc -m32'" on an x86-64 machine) so
that .elc file had been built assuming 32-bit values for
most-negative-fixnum and most-positive fixnum. When I then re-ran
'configure' for a 64-bit platform the .elc files were not automatically
rebuilt for it (they're supposed to be machine-independent, right?) and
so the optimizations were incorrect for a 64-bit platform and the tests
failed.
What's a good way to fix this problem, while still testing everything
that comp-tests.el wants to test?
