[issue8265] test_float fails on ARM Linux EABI with soft floating point

Matthias Klose added the comment: I checked with gcc-4.4 from the 4.4 branch, and with a recent build from the trunk. The check fails with -O0, and succeeds with -O1 and higher. Is the testcode from r82957 really using the optimization flags? -- _

[issue8265] test_float fails on ARM Linux EABI with soft floating point

Mark Dickinson added the comment: I notice (again) that these failures occur on the 2.6 and 3.1 buildslaves (where the debug build includes the -O2 compilation flag), but not the 2.7 or py3k buildslaves. So again this looks like a compiler optimization bug. This should really be reported ups

David Kirkby added the comment: I'm seeing this failure on both Solaris 10 (SPARC processor) in 32-bit mode and OpenSolaris 06/2009 (Intel Xeon) in 64-bit mode using Python 2.6.4. So it is not just an ARM Linux issue. See http://trac.sagemath.org/sage_trac/ticket/9297 http://trac.sagemath.

Mark Dickinson added the comment: I made a couple of experimental checkins to the release26-maint branch (I didn't want to do a temporary checkin to the trunk with a release imminent): see r79560 (which didn't work :) and its fix in r79601. Results: MIN = 2.2250738585072014e-308 TINY =

Matthias Klose added the comment: the buildbot labeled "ARM Linux 3.x" is an ARM EABI as well, compiler defaults -march=armv7 -math=vfp -float-abi=softfp. The failing test_float test is an ARM EABI, armv4, ARM mode, soft floating point. I never did see the test_float test suceed on this plat
