* ARM: Fix clone build for ARMv4Will Newton2014-01-242-7/+7
| | | | | | | | | | | | | | | ARMv4 does not have the blx instruction, so use the BLX macro which handles abstracting this for us. Build tested for armv7, armv4t and armv4. ports/ChangeLog.arm: 2014-01-24 Will Newton <will.newton@linaro.org> [BZ #16499] * sysdeps/unix/sysv/linux/arm/clone.S: Use BLX macro instead of blx instruction directly.

* ARM: Don't apply pointer encryption to the frame pointerWill Newton2014-01-145-11/+20
| | | | | | | | | | | | | | | | | | | | | The frame pointer register is rarely used for that purpose on ARM and applications that look at the contents of the jmp_buf may be relying on reading an unencrypted value. For example, Ruby uses the contents of jmp_buf to find the root set for garbage collection so relies on this pointer value being unencrypted. Without this patch the Ruby testsuite fails with a segmentation fault. ports/ChangeLog.arm: 2013-01-14 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S: Don't apply pointer encryption to fp register. * sysdeps/arm/setjmp.S: Likewise. * sysdeps/arm/include/bits/setjmp.h (JMP_BUF_REGLIST): Add fp to register list, remove a4. * sysdeps/unix/sysv/linux/arm/sysdep.h (PTR_MANGLE_LOAD): New macro.

* Use separate libc.abilist for MIPS o32 soft float.Joseph Myers2014-01-073-0/+2268
| | | | | | | | | | | | | | | | | | | | Examining MIPS test results showed an ABI test failure that I must have missed in 2.18 testing: hard-float and soft-float o32 no longer have the same set of symbols (because of the __mips_fpu_getcw and __mips_fpu_setcw functions, present for hard-float only, used by fpu_control.h for hard-float MIPS16) and so need separate ABI test baselines (they always were ABI-incompatible - the function-calling interface is different - but previously had the same set of symbols and versions so didn't need separate baselines). Tested for hard-float and soft-float o32. * sysdeps/unix/sysv/linux/mips/mips32/nptl/libc.abilist: Move to .... * sysdeps/unix/sysv/linux/mips/mips32/fpu/nptl/libc.abilist: ... here. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/nptl/libc.abilist: New file.

* ia64: add __ prefix to pt_all_user_regs/ia64_fpreg [BZ #762]Mike Frysinger2014-01-064-5/+18
| | | | | | | | | | | | This addresses a long standing collision between userspace headers and kernel headers only on ia64 systems. All other types have a __ prefix in the ptrace headers except these two. Let's finally namespace these. Verified that at least strace still builds after this change, as well as after deleting all the struct hacks it has specifically for ia64.

* ptrace.h: add __ prefix to ptrace_peeksiginfo_argsMike Frysinger2014-01-066-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | All the other ptrace structures in this file have a __ prefix except this new one. This in turn causes build problems for most packages that try to use ptrace such as strace: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../linux/x86_64 -I../../linux \ -I./linux -Wall -Wwrite-strings -g -O2 -MT process.o -MD -MP \ -MF .deps/process.Tpo -c -o process.o ../../process.c In file included from ../../process.c:63:0: /usr/include/linux/ptrace.h:58:8: error: redefinition of 'struct ptrace_peeksiginfo_args' struct ptrace_peeksiginfo_args { ^ In file included from ../../defs.h:159:0, from ../../process.c:37: /usr/include/sys/ptrace.h:191:8: note: originally defined here struct ptrace_peeksiginfo_args ^ Since this struct was introduced in glibc-2.18, there shouldn't be any real regressions with adding the __ prefix.

* ia64: fix build failure after async tls updatesMike Frysinger2014-01-042-4/+11
| | | | | | | | | | The recent commit 7f507ee17aee720fa423fa38502bc3caa0dd03d7 added a new local variable "offset" to tls_get_addr_tail. This conflicts with the ia64 code which also declares an offset code inline in this func. So have the ia64 code rename its local vars with a prefix that shouldn't collide with anything else in the future. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | The sp check has to be moved up to the start of the func since it now makes a system call and that'll clobber a lot of registers. URL: https://sourceware.org/bugzilla/show_bug.cgi?id=16372 Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | The new tst-setjmp-fp test has been failing on IA64 because the setjmp and longjmp helpers take care of saving/restoring the fpsr register. Per the C standards, this is incorrect, so disable that logic. URL: https://sourceware.org/bugzilla/show_bug.cgi?id=16379 Signed-off-by: Mike Frysinger <vapier@gentoo.org>
