I don't know if it has broken it on other platforms too. Also I now get about 30 failures on IA64 for gcc.dg/torture/builtin-math-2.c. FAIL: gcc.dg/torture/builtin-math-2.c -O0 scan-tree-dump-times original "fma " 3 (30 or so more reports for fmaf and fmal and at various options) It looks like the expand file contains FMA_EXPR instead of the builtin_fma calls, as mentioned in the powerpc bug report for pr46353. I tried various combinations of -ffp-contract and -fno-fused-madd on this test but none had any effect. Steve Ellcey sje@cup.hp.com
