From 4ad186c5ef61477030ca37372f9d6c6d03681015 Mon Sep 17 00:00:00 2001 From: grischka Date: Mon, 6 Jan 2014 19:07:08 +0100 Subject: [PATCH] i386: use __fixdfdi instead of __tcc_cvt_ftol Variants __fixsfdi/__fixxfdi are not needed for now because the value is converted to double always. Also: - remove __tcc_fpinit for unix as it seems redundant by the __setfpucw call in the startup code - avoid reference to s->runtime_main in cross compilers - configure: fix --with-libgcc help - tcctok.h: cleanup --- configure | 2 +- i386-gen.c | 28 ++++++++----------- lib/libtcc1.c | 39 ++++++++++++++------------ tccelf.c | 4 +-- tccpe.c | 2 ++ tcctok.h | 89 ++++++++++++++++++++++++++++++----------------------------- 6 files changed, 84 insertions(+), 80 deletions(-) mode change 100755 => 100644 configure diff --git a/configure b/configure old mode 100755 new mode 100644 index cc8ca5a3..8c44e5c6 --- a/configure +++ b/configure @@ -273,7 +273,7 @@ Advanced options (experts only): --strip-binaries strip symbol tables from resulting binaries --disable-static make libtcc.so instead of libtcc.a --disable-rpath disable use of -rpath with the above - --with-libgcc use libgcc_s.so.1 instead of libtcc.a in dynamic link + --with-libgcc use libgcc_s.so.1 instead of libtcc1.a in dynamic link --enable-mingw32 build windows version on linux with mingw32 --enable-cygwin build windows version on windows with cygwin --enable-cross build cross compilers diff --git a/i386-gen.c b/i386-gen.c index 2eb69227..4c4a54bf 100644 --- a/i386-gen.c +++ b/i386-gen.c @@ -581,14 +581,6 @@ ST_FUNC void gfunc_prolog(CType *func_type) func_bound_offset = lbounds_section->data_offset;
