Hi,
currently, our software (www.lejos.org, build with a gcc 4.3.x based
arm-elf toolchain) manages to compare floats correctly most of the time.
But sometimes, the comparisons don't have the expected result.
Basically, comparisons behave non-deterministically.
We believe, that this is the result of a Bug in ieee754-{df,sf}.S.
A fix that seems to be related has been committed on June 5th, 2009, SVN
revision 148210. The commit comment was:
gcc/
* config/arm/ieee754-df.S (cmpdf2): Avoid writing below SP.
* config/arm/ieee754-sf.S (cmpsf2): Likewise.
Is gcc 4.3 still supported? Will there be release of gcc 4.3.7?
If yes, may I ask that you backport the fix to 4.3.x?
I didn't check the other branches (4.4, 4.5, or 4.6), but if it's
missing there then it should definitely be backported to these branches
as well.
Kind Regards,
Sven
