From 6600049466b586e3decaf24bd70c06b21382cf98 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 6 May 1998 14:43:15 +0000 Subject: Update. 1998-04-16 07:42 Geoff Keating * Makeconfig [!build-static]: Link `static' binaries with libc_pic.a. Still need *FLAGS-.o because we still sometimes build .o files. * db2/Makefile: Don't build libndbm.a if !build-static. 1998-04-16 07:42 Geoff Keating * configure.in: New test for broken gcc on PowerPC. * sysdeps/powerpc/atomicity.h: Use result of test. * linuxthreads/sysdeps/powerpc/pt-machine.h: Use result of test. * math/libm-test.c: Update many of the epsilon to match actual performance. * sysdeps/libm-ieee754/e_exp.c: Reduce the number of branches. * sysdeps/libm-ieee754/e_expf.c: Likewise. * sysdeps/libm-ieee754/s_exp2.c: Likewise. * sysdeps/libm-ieee754/s_exp2f.c: Likewise. * sysdeps/libm-ieee754/e_pow.c: Correct typo. * sysdeps/powerpc/elf/libc-start.c: New file. * sysdeps/powerpc/elf/start.S: New file, use libc-start. * sysdeps/powerpc/elf/start.c: Delete. * sysdeps/unix/sysv/linux/powerpc/Dist: Remove syscall.h * sysdeps/unix/sysv/linux/powerpc/syscall.h: Delete. It was unused. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Correct previous few patches. --- configure.in | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'configure.in') diff --git a/configure.in b/configure.in index e7dfcc59a3..9866d4b8aa 100644 --- a/configure.in +++ b/configure.in @@ -921,6 +921,18 @@ else fi fi +if test "$host_cpu" = powerpc ; then +# Check for a bug present in at least versions 2.8.x of GCC +# and versions 1.0.x of EGCS. +AC_CACHE_CHECK(whether clobbering cr0 causes problems,libc_cv_c_asmcr0_bug,[dnl +AC_TRY_COMPILE([int tester(int x) { asm ("" : : : "cc"); return x & 123; }],, + libc_cv_c_asmcr0_bug='no', + libc_cv_c_asmcr0_bug='yes')]) +if test "$libc_cv_c_asmcr0_bug" != 'no'; then + AC_DEFINE(BROKEN_PPC_ASM_CR0) +fi +fi + AC_CACHE_CHECK(for DWARF2 unwind info support, libc_cv_gcc_dwarf2_unwind_info, [cat > conftest.c <
