* PowerPC64 ELFv2 ABI 2/6: Remove function descriptorsUlrich Weigand2013-12-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the ELFv2 ABI feature to remove function descriptors. See this GCC patch for in-depth discussion: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01141.html This mostly involves two types of changes: updating assembler source files to the new logic, and updating the dynamic loader. After the refactoring in the previous patch, most of the assembler source changes can be handled simply by providing ELFv2 versions of the macros in sysdep.h. One somewhat non-obvious change is in __GI__setjmp: this used to "fall through" to the immediately following __setjmp ENTRY point. This is no longer safe in the ELFv2 since ENTRY defines both a global and a local entry point, and you cannot simply fall through to a global entry point as it requires r12 to be set up. Also, makecontext needs to be updated to set up registers according to the new ABI for calling into the context's start routine. The dynamic linker changes mostly consist of removing special code to handle function descriptors. We also need to support the new PLT and glink format used by the the ELFv2 linker, see: https://sourceware.org/ml/binutils/2013-10/msg00376.html In addition, the dynamic linker now verifies that the dynamic libraries it loads match its own ABI. The hack in VDSO_IFUNC_RET to "synthesize" a function descriptor for vDSO routines is also no longer necessary for ELFv2.

* PowerPC: Fix vDSO missing ODP entriesAdhemerval Zanella2013-11-081-5/+25
| | | | | | | This patch fixes the vDSO symbol used directed in IFUNC resolver where they do not have an associated ODP entry leading to undefined behavior in some cases. It adds an artificial OPD static entry to such cases and set its TOC to non 0 to avoid triggering lazy resolutions.
* PowerPC SIGSTKSZAlan Modra2013-10-041-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00093.html This copies the sparc version of sigstack.h, which gives powerpc #define MINSIGSTKSZ 4096 #define SIGSTKSZ 16384 Before the VSX changes, struct rt_sigframe size was 1920 plus 128 for __SIGNAL_FRAMESIZE giving ppc64 exactly the default MINSIGSTKSZ of 2048. After VSX, ucontext increased by 256 bytes. Oops, we're over MINSIGSTKSZ, so powerpc has been using the wrong value for quite a while. Add another ucontext for TM and rt_sigframe is now at 3872, giving actual MINSIGSTKSZ of 4000. The glibc testcase that I was looking at was tst-cancel21, which allocates 2*SIGSTKSZ (not because the test is trying to be conservative, but because the test actually has nested signal stack frames). We blew the allocation by 48 bytes when using current mainline gcc to compile glibc (le ppc64). The required stack depth in _dl_lookup_symbol_x from the top of the next signal frame was 10944 bytes. I guess you'd want to add 288 to that, implying an actual SIGSTKSZ of 11232. * sysdeps/unix/sysv/linux/powerpc/bits/sigstack.h: New file.
* PowerPC: fix backtrace to handle signal trampolinesAdhemerval Zanella2013-08-201-0/+7
| | | | | | This patch fixes backtrace for PPC32 and PPC64 to correctly handle signal trampolines. The 'debug/tst-backtrace6.c' also check for SA_SIGINFO handling, where is triggers another vDSO symbols for PPC32.
* PowerPC: Add time vDSO supportAdhemerval Zanella2013-05-031-2/+4
| | | | | | | | PowerPC kernel now provides a vDSO implementation for time syscall (commit fcb41a2030abe0eb716ef0798035ef9562097f42). This patch changes time syscall wrapper to use the vDSO when available. It also changes the default non vDSO time on PowerPC to use sysdeps/posix/time.c (since gettimeofday is a vDSO call).
