Fw: [Bug target/67877] New: Split stack needs to be support for AARCH64

by Pinski, Andrew

FYI. This is a parity feature with both PowerPC64 and x86_64. Needed to support GCCgo. Note full gold support is needed too. ---------- Forwarded message ---------- From: pinskia at gcc dot gnu.org <gcc-bugzilla(a)gcc.gnu.org> Date: Tue, Oct 6, 2015 at 3:30 PM Subject: [Bug target/67877] New: Split stack needs to be support for AARCH64 To: gcc-bugs(a)gcc.gnu.org https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67877 Bug ID: 67877 Summary: Split stack needs to be support for AARCH64 Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: pinskia at gcc dot gnu.org Target Milestone: --- Target: aarch64-linux-gnu* To support gccgo better split stack should be implemented.

# Progress # * TCWG-373, Aarch64 non-stop debugging (or displaced stepping). [2/10] Patches V1 are ready for upstream submission, but find opcodes has already interfaces to decode instructions, so decide to use opcodes for aarch64 GDB first. * TCWG-387, one patch exposing one opcode interface is pushed in. [4/10] Switch software single step code for aarch64 to using opcodes interface. Patch is pushed in. Rewriting prologue analyser to use opcode interface too. * TCWG-159, Kernel awareness in GDB. [1/10] Resume the work as Peter Griffin has cycles to do so. We are happy with the plan so far. * Review arm software breakpoint in GDBserver patches. [1/10] * Misc, [2/10] # Plan # * TCWG-387, TCWG-373 -- Yao

== Progress == 2 days off (4/10) * Infrastructure/validation: (3/10) further checking of cross-testing results stability on aarch64-linux - found a workaround for a timestamp problem (_Pragma3 testcase) - looked at c11-atomic-exec-5 whose execution time ranges between 1s and 1h :-) - forcing make check to -j8 seems to work well, will work on a nicer improvement * reported and briefly looked at failure in a new libstdc++ test (directory_iterator) on armv5t * Misc (conf calls, meetings, emails, ....) (2/10) * Internal (1/10) - GNU linker patch review

[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 5.1 2015.08-rc2

by Ryan Arnold

The Linaro Toolchain Working Group is pleased to announce the availability of the Linaro Stable Binary Toolchain Release-Candidate GCC 5.1-2015.08-rc2 Archives. http://snapshots.linaro.org/components/toolchain/binaries/5.1-2015.08-rc2/ These archives provide cross-toolchain executables (compiler, debugger, linker, etc.) and shared libraries (libstdc++, libc, etc.) that target ARM or Aarch64 GNU/Linux and bare-metal environments. The cross-toolchain binaries execute on a Linux or MS Windows (under mingw32) host operating-system. Please evaluate this release-candidate for correctness. Linaro will shortly spin the Linaro GCC 5.1-2015.08 release if this release-candidate passes stakeholder validation. For bugs related to this release-candidate please email linaro-toolchain(a)lists.linaro.org or file a bug at http:// https://bugs.linaro.org/enter_bug.cgi?product=Linux%20Binary%20toolchain NEWS * 2015.08-rc2 * The Linaro 2015.08-rc2 release-candidate binary toolchain is based on the Linaro GCC-5.1-2015.08-rc1 release-candidate source archive. The only changes between 2015.08-rc1 and 2015.08-rc2 were the following changes in how the binary toolchains were built. The compiler itself was not changed. * x86_64 hosted, armv8l-linux-gnueabihf targetted cross toolchains are now correctly configured. This was broken in 2015.08-rc1. The cross-compiler targetting armv8l-linux-gnueabihf is now correctly configured with --with-arch=armv8-a --with-fpu=neon-fp-armv8 --with-float=hard --disable-multilib --enable-multiarch. * Glibc’s slibdir and libdir were once again modified to address Linaro Bugzilla 1717 – Linaro-4.9-2015.05 moved system libs from /libc/lib/ to /libc/usr/lib/ which breaks things. The following are now the correct locations: libdir=lib/ (linker-scripts and static archives) slibdir=usr/lib/ (shared objects) rtlddir=lib/ (dynamic linker) * 2015.08-rc1 * x86_64 hosted, armv8l-linux-gnueabihf targetted cross toolchain now provided. Delivering on REQ-477 – Enable x86_64 to Aarch32 (32-bit ARMv8-A) cross binary toolchain product release and CARD-1637 – Enable Aarch32 (32-bit ARMv8-A) cross binary toolchain product releases , armv8l-linux-gnueabihf targetted toolchains are now available as part of this release-candidate. * Python support in GDB for both Linux and Mingw32 (32-bit windows). Delivered as requested in the linaro-toolchain mailing list post title – windows binary builds with gdb-python enabled?. * Added missing expat support to GDB. This addresses the following linaro-toolchain mailing list post – "Missing expat support in GDB 7.8 multi-lib enablement for arm bare-metal targets." * A fix for multilib enablement in baremetal toolchains (as described in ABE Review 6862). * Library Paths are now congruent with older Linaro Toolchain path layouts. This addresses Linaro Bugzilla 1717 – Linaro-4.9-2015.05 moved system libs from /libc/lib/ to /libc/usr/lib/ which breaks things. libdir=lib/ (shared objects) slibdir=usr/lib/ (static libraries) rtlddir=lib/ (dynamic linker)
