--- Comment #1 from rguenth at gcc dot gnu dot org 2010-04-01 13:48 --- Because we only have an optab for LT (reversed UNGE), but FLOAT_LIB_COMPARE_RETURNS_BOOL is false. Without -fno-trapping-math we use LT from the start which works. I suppose FLOAT_LIB_COMPARE_RETURNS_BOOL should return true for decimal float modes on x86? -- rguenth at gcc dot gnu dot org changed: What|Removed |Added CC||hjl at gcc dot gnu dot org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2010-04-01 13:48:17 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43610

--- Comment #2 from rguenth at gcc dot gnu dot org 2010-04-01 13:51 --- And I believe the regression is because of either cond-optab or expand-from-SSA which causes us no longer to fallback to expand a UNORD b || a = b. -- rguenth at gcc dot gnu dot org changed: What|Removed |Added CC||bonzini at gnu dot org, matz ||at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43610
