------- Comment #1 from guillaume dot melquiond at ens-lyon dot fr 2007-04-11 09:43 ------- As a follow-up, it seems the wrong code is generated during the "combine" pass: the RTL after the "life1" pass is still correct: "(-b) * a + c" (whether -frounding-math is enabled or not), while the RTL after the "combine" pass is "c - a * b".
