From 76480b6b18868754fc95ff41d02885898c54367f Mon Sep 17 00:00:00 2001 From: Nicolás Reynolds Date: Tue, 17 Apr 2012 20:37:01 -0300 Subject: Updating the cross toolchain for mips64el Added patches from upstream and diff'ed with them. Binutils and linux-libre-api-headers are already built. GCC Core builts but `mips64el-unknown-linux-gnu-gcc -v dummy.c` fails because of missing -EL on i686-pc-linux-gnu-as. Exporting mips64el-...-binutils to the PATH solves the problem but mips64el-...-ld fails with missing crt*. No idea why target gcc decides to use the host as instead of the target one, since the PKGBUILD hasn't fundamentally changed. --- .../glibc-2.15-avx.patch | 196 +++++++++++++++++++++ 1 file changed, 196 insertions(+) create mode 100644 cross/cross-mips64el-unknown-linux-gnu-glibc-headers/glibc-2.15-avx.patch (limited to 'cross/cross-mips64el-unknown-linux-gnu-glibc-headers/glibc-2.15-avx.patch') diff --git a/cross/cross-mips64el-unknown-linux-gnu-glibc-headers/glibc-2.15-avx.patch b/cross/cross-mips64el-unknown-linux-gnu-glibc-headers/glibc-2.15-avx.patch new file mode 100644 index 000000000..5439da8d0 --- /dev/null +++ b/cross/cross-mips64el-unknown-linux-gnu-glibc-headers/glibc-2.15-avx.patch @@ -0,0 +1,196 @@ +diff --git a/sysdeps/x86_64/fpu/multiarch/e_atan2.c b/sysdeps/x86_64/fpu/multiarch/e_atan2.c +index 6867c6e..3a615fc 100644 +--- a/sysdeps/x86_64/fpu/multiarch/e_atan2.c ++++ b/sysdeps/x86_64/fpu/multiarch/e_atan2.c +@@ -14,7 +14,7 @@ extern double __ieee754_atan2_fma4 (double, double); + + libm_ifunc (__ieee754_atan2, + HAS_FMA4 ?
