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/Archi.v | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'powerpc/Archi.v') diff --git a/powerpc/Archi.v b/powerpc/Archi.v index 058b057f..cf1a0fe3 100644 --- a/powerpc/Archi.v +++ b/powerpc/Archi.v @@ -43,3 +43,7 @@ Global Opaque big_endian default_pl_64 choose_binop_pl_64 default_pl_32 choose_binop_pl_32 float_of_single_preserves_sNaN. + +(** Can we use the 64-bit extensions to the PowerPC architecture? *) +Parameter ppc64: bool. + -- cgit From f5bb397acd12292f6b41438778f2df7391d6f2fe Mon Sep 17 00:00:00 2001 From: Michael Schmidt Date: Wed, 14 Oct 2015 15:26:56 +0200 Subject: bug 17392: remove trailing whitespace in source files --- powerpc/Archi.v | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'powerpc/Archi.v') diff --git a/powerpc/Archi.v b/powerpc/Archi.v index cf1a0fe3..8ff11f08 100644 --- a/powerpc/Archi.v +++ b/powerpc/Archi.v @@ -25,13 +25,13 @@ Definition big_endian := true.
