2014-02-10Move tilegx, tilepro, and linux-generic from ports to libc.Chris Metcalf
I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy, along with the linux-generic ports infrastructure. Beyond the README update, the move was just git mv ports/sysdeps/tile sysdeps/tile git mv ports/sysdeps/unix/sysv/linux/tile \ sysdeps/unix/sysv/linux/tile git mv ports/sysdeps/unix/sysv/linux/generic \ sysdeps/unix/sysv/linux/generic I updated the relevant ChangeLogs along the lines of the ARM move in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that there were no changes in "objdump -dr" output in the shared objects.
2014-02-08Move arm from ports to libc.Joseph Myers
I've moved the ARM port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/arm sysdeps/arm git mv ports/sysdeps/unix/arm sysdeps/unix/arm git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.arm similar to that at the top of ChangeLog.powerpc. There is deliberately no NEWS change, as I think it makes the most sense to put in a general note above all ports having moved if we can achieve that for 2.20. Tested that disassembly of installed shared libraries for arm is the same before and after this patch, except for data (not instructions) in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the path by which that file is found, and so by which it appears in the assertion message, changes as a result of the move). * sysdeps/arm: Move directory from ports/sysdeps/arm. * sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm. * sysdeps/unix/sysv/linux/arm: Move directory from ports/sysdeps/unix/sysv/linux/arm. * README: Update listing for arm-*-linux-gnueabi. ports/ChangeLog.arm: * sysdeps/arm: Move directory to ../sysdeps/arm. * sysdeps/unix/arm: Move directory to ../sysdeps.arm. * sysdeps/unix/sysv/linux/arm: Move directory to ../sysdeps/unix/sysv/linux/arm.
2014-02-08Move shared sysdeps files from alpha to arm.Joseph Myers
This patch prepares for moving arm from ports to libc (see overall plan at <https://sourceware.org/ml/libc-alpha/2014-01/msg00373.html> and discussion of ordering starting at <https://sourceware.org/ml/libc-ports/2014-01/msg00071.html>) by reversing the #include order between arm and alpha, so that arm can move early as a test for the general pattern of moving architectures. MicroBlaze files (that used the same alpha files) were made to include the files directly from their new locations rather than indirecting. Tested that disassembly of installed shared libraries for arm is the same before and after this patch. * sysdeps/unix/sysv/linux/alpha/msgctl.c: Move to sysdeps/unix/sysv/linux/arm/msgctl.c and #include that file. * sysdeps/unix/sysv/linux/alpha/semctl.c: Move to sysdeps/unix/sysv/linux/arm/semctl.c and #include that file. * sysdeps/unix/sysv/linux/alpha/shmctl.c: Move to sysdeps/unix/sysv/linux/arm/shmctl.c and #include that file. * sysdeps/unix/sysv/linux/arm/msgctl.c: Move from sysdeps/unix/sysv/linux/alpha/msgctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/arm/semctl.c: Move from sysdeps/unix/sysv/linux/alpha/semctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/arm/shmctl.c: Move from sysdeps/unix/sysv/linux/alpha/shmctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/microblaze/msgctl.c: Include sysdeps/unix/sysv/linux/arm/msgctl.c instead of sysdeps/unix/sysv/linux/alpha/msgctl.c. * sysdeps/unix/sysv/linux/microblaze/semctl.c: Include sysdeps/unix/sysv/linux/arm/semctl.c instead of sysdeps/unix/sysv/linux/alpha/semctl.c. * sysdeps/unix/sysv/linux/microblaze/shmctl.c: Include sysdeps/unix/sysv/linux/arm/shmctl.c instead of sysdeps/unix/sysv/linux/alpha/shmctl.c.
2014-02-08Remove am33 port.Joseph Myers
This patch removes the am33 port (no other port #includes any files from it), as previously discussed (see <https://sourceware.org/ml/libc-ports/2014-01/msg00046.html>).

2014-01-24ARM: Fix clone build for ARMv4Will Newton
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.

2014-01-14ARM: Don't apply pointer encryption to the frame pointerWill Newton
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.
2014-01-10ARM: Disable compat mcount code when unneeded.Roland McGrath
2014-01-07Use separate libc.abilist for MIPS o32 soft float.Joseph Myers
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.

2014-01-06ia64: add __ prefix to pt_all_user_regs/ia64_fpreg [BZ #762]Mike Frysinger
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.

2014-01-06ptrace.h: add __ prefix to ptrace_peeksiginfo_argsMike Frysinger
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.

2014-01-04ia64: fix build failure after async tls updatesMike Frysinger
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>
