From 378ac3925503e6efd24cc34796e85d95c031e72d Mon Sep 17 00:00:00 2001 From: Xavier Leroy Date: Sun, 13 Sep 2015 11:44:32 +0200 Subject: Use PowerPC 64 bits instructions (when available) for int<->FP conversions. Also: implement __builtin_isel on non-EREF platforms with a branch-free instruction sequence. Also: extend ./configure so that it recognizes "ppc64-" and "e5500-" platforms in addition to "ppc-". --- powerpc/extractionMachdep.v | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'powerpc/extractionMachdep.v') diff --git a/powerpc/extractionMachdep.v b/powerpc/extractionMachdep.v index b448e3d2..b0f05536 100644 --- a/powerpc/extractionMachdep.v +++ b/powerpc/extractionMachdep.v @@ -23,3 +23,11 @@ Extract Constant Asm.symbol_is_rel_data => "C2C.atom_is_rel_data".
