* gcc: support avrMatthew Bauer2018-10-29
| | | | | | | | | | | | | | | | | | - respect libc’s incdir and libdir - make non-unix systems single threaded - set LIMITS_H_TEST to false for avr - misc updates to support new libc’s - use multilib with avr For threads we want to use: - posix on unix systems - win32 on windows - single on everything else For avr: - add library directories for avrlibc - to disable relro and bind - avr5 should have precedence over avr3 - otherwise gcc uses the wrong one

| * gcc: fix libgomp to not use initial-execWill Dietz2018-09-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only apply w/musl since while it's wrong everywhere it apparently hasn't broken things entirely w/glibc so keep things as they were. Patch regenerated from original so that it applies which isn't saying much since it's simple :). Source: https://patchwork.ozlabs.org/patch/154298/ IRC chat on #musl with Rich and others endorses this, at least at the conceptual level of no shared library should be using initial-exec TLS. Fixes various uses of libgomp that previously crashed (before 1.1.20) or encounter errors (post-1.1.20), such as pythonPackages.cython .

* gcc: Clarify Disabling libmpx in cross stage staticJohn Ericson2018-09-18
| | | | | | This isn't a MUSL thing, but just needed for cross compilation to x86. No one had tried this when all cross compilation was to linux + glibc, hence why no one noticed this until recently.

| | | | | | | | | | | | | | | | | | ARM ABIs now have a float field. This is used as a fallback to lessen our use of `platform.gcc.float`. I didn't know what the MIPs convention is so I kept using `platform.gcc.float` in that case.

This is confusing to non packagers though, because Aarch64 is an ARM instruction set. The official ARM overview for ARMv8[1] is surprisingly not confusing, given the overall state of affairs for ARM naming conventions, and offers us a solution. It divides the nomenclature into three levels: ``` ISA: ARMv8 {-A, -R, -M} / \ Mode: Aarch32 Aarch64 | / \ Encoding: A64 A32 T32 ``` At the top is the overall v8 instruction set archicture. Second are the two modes, defined by bitwidth but differing in other semantics too, and buttom are the encodings, (hopefully?) isomorphic if they encode the same mode. The 32 bit encodings are mostly backwards compatible with previous non-Thumb and Thumb encodings, and if so we can pun the mode names to instead mean "sets of compatable or isomorphic encodings", and then voilà we have nice names for 32-bit and 64-bit arm instruction sets which do not use the word ARM so as to not confused either laymen or experienced ARM packages.

Patches were pulled from H.J. Lu's backport branch to 4.9 (hjl/indirect/gcc-4_9-branch), available at https://github.com/hjl-tools/gcc/tree/hjl/indirect/gcc-4_9-branch/master. Upstream GCC does not apply patches to anything older than the gcc-6-branch. H.J. Lu is the author of the upstream retpoline commits as well. Several Linux distributions already backported these patches to GCC 4 branches and some old kernels (3.13 for instance) have been recompiled with these GCC patches. These kernels only allow to load kernel modules that are compiled with the retpoline support.
