Now do it for all systems, including OpenBSD. This affects both 32-bit and powerpc64 code. ok kettenis@ Switch powerpc clang to -msvr4-struct-return, like gcc. 2020-03-04T18:44:38Z gkoehler gkoehler@openbsd.org 2020-03-04T18:44:38Z urn:sha1:9c510017451e6e3b2caf02948cc3de82e92d6fd2 Add these options from gcc to clang: -maix-struct-return # return all structs in memory -msvr4-struct-return # return small structs in r3/r4 ok mortimer@ jca@ deraadt@ Add retguard for octeon/mips64. 2019-10-25T00:40:56Z mortimer mortimer@openbsd.org 2019-10-25T00:40:56Z urn:sha1:52446778f86252aa4533d0b08b871472df4e84f6 For this architecture we use separate retguard prologue and epilogue code for static or PIC code. In the PIC case we use some additional code before the retguard epilogue to recover the function start address and the GOT pointer in order to get the per-function random cookie. Much thanks to visa@ for suggestions and advice making it all work. ok deraadt@ visa@ Make clang emit the proper path to our libcompiler_rt.a when asked to. 2019-09-28T22:34:04Z patrick patrick@openbsd.org 2019-09-28T22:34:04Z urn:sha1:6fa5adb2b628678ac733f1abb64262f2ded86284 Change of behaviour in latest clang upgrade noticed by jsing@ during the Go port update, where --print-libgcc-file-name is being used which prints the compiler-rt path. ok kettenis@ Merge LLVM 8.0.1 release. 2019-09-01T16:37:21Z patrick patrick@openbsd.org 2019-09-01T16:37:21Z urn:sha1:d3df0c01b52bb561f932539d0321079fcb70e869 Tested in snaps and package builds Tested on amd64 by naddy@ Tested on arm64 by patrick@ Tested on octeon by visa@ Import LLVM 8.0.1 release including clang, lld and lldb. 2019-09-01T16:27:59Z patrick patrick@openbsd.org 2019-09-01T16:27:59Z urn:sha1:b19884b112052f3bf5ff9551374fbd840e2339f2 In LLVM 8 somebody had the glorious idea to enable the integrated assembler 2019-06-26T14:39:12Z claudio claudio@openbsd.org 2019-06-26T14:39:12Z urn:sha1:e75df510872593510780f5aa14b5c417a6944d46 for OpenBSD sparc64. The problem is that the integrated assembler is not even able to compile the .S files in lib/csu or lib/libc so revert this and use gas again. Fixes build issues with clang on sparc64.
