ffec3151 - Convert gnu to using SRCTOP

Sun, 12 Mar 2017 18:59:16 +0000

Convert gnu to using SRCTOPPrefer SRCTOP over CURDIR/../../contrib, etc. However, retain the "upone level" instances of ../ because they are really relative to thispart of the tree and not a means to find the root of the tree. Assuch, it's better to leave them since that further the goal of beingable to move directories if watned to in the future.Differential Revision: https://reviews.freebsd.org/D9932Sponsored by: NetflixSilence On: arch@ (twice) List of files: /freebsd-12.1/gnu/lib/libgomp/Makefile

dc9b124d - Create a new MACHINE_ARCH for Freescale PowerPC e500v2

Sat, 22 Oct 2016 01:57:15 +0000

Create a new MACHINE_ARCH for Freescale PowerPC e500v2Summary:The Freescale e500v2 PowerPC core does not use a standard FPU.Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processorunit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with thestock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.Additionaly, the SPE opcodes overlap with Altivec, so these are mutuallyexclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, wascreated with the same function set as in powerpc/powerpc/altivec.c, so itbecomes effectively a drop-in replacement. setjmp/longjmp were modified to savethe upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible bythe SPE).Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does notsupport double-precision floating point.Also, without a new MACHINE_ARCH it would be impossible to provide binarypackages which utilize the SPE.Additionally, no work has been done to support ports, work is needed for this.This also means no newer gcc can yet be used. However, gcc's powerpc supporthas been refactored which would make adding a powerpcspe-freebsd target veryeasy.Test Plan:This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222(P1022-based) board, compiled against the new ABI. Base system utilities(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to bootmultiuser.Reviewed By: bdrewery, impRelnotes: yesDifferential Revision: https://reviews.freebsd.org/D5683 List of files: /freebsd-12.1/gnu/lib/libgomp/Makefile

cd2ae253 - Retire TARGET_ABI.

Fri, 07 Jan 2011 20:26:33 +0000

Retire TARGET_ABI.Implement MACHINE_ARCH=mips64e[lb] to build N64 images. This replacesMACHINE_ARCH=mipse[lb] TARGET_ABI=n64.MACHINE_ARCH=mipsn32e[lb] has been added, but currently requiresWITHOUT_CDDL due to atomic issues in libzfs. I've not investigatedthis much, but implemented this to preserve as much of the TARGET_ABIfunctionality that I could. Since its presence doesn't affect theworking cases, I've kept it in for now.Added mips64e[lb] to make universe, so more kernels build.And I think this (finally) closes the curtain on the tbemd tree.

5619a3e4 - Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.

Wed, 02 Jun 2010 11:06:03 +0000

Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.o) Add TARGET_ABI to the MIPS toolchain build process. This sets the default ABI to one of o32, n32 or n64. If it is not set, o32 is assumed as that is the current default.o) Set the default GCC cpu type to any specified TARGET_CPUTYPE. This is necessary to have a working "cc" if e.g. mips64 is specified, as binutils will refuse to link objects using different ISAs in some cases.o) Add support for n32 and n64 ABIs to binutils and GCC.o) Add additional required libgcc2 stubs for n32 and n64.o) Add support for the "mips64r2" architecture to GCC. Add the "octeon"o) When static linking, wrap default libraries in --start-group and --end-group. This is required for static linking to work on n64 with the interdependencies between libraries there. This is what other OSes that support n64 seem to do, as well.o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the former being what libgcc, etc., check and the latter seemingly being a misspelling of a hand merge from a Linux spec.o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default ISA from the ABI. Our old defaults were too liberal and assumed that 64-bit ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to the MIPS32 ISA, when we are supporting or will support some systems based on earlier 32-bit and 64-bit ISAs, most notably MIPS-III.o) Merge a new opcode file (and support code) from a later version of binutils and add flags and code necessary to support Octeon-specific instructions. This should also make merging opcodes for other modern architectures easier.Reviewed by: imp List of files: /freebsd-12.1/gnu/lib/libgomp/Makefile

afb57df6 - Update bmake glue to build GCC 4.2.

Sat, 19 May 2007 04:25:59 +0000

Update bmake glue to build GCC 4.2.Also: Switch FreeBSD to use libgcc_s.so.1. Use dl_iterate_phdr to locate shared objects' exception frame info instead of depending on older register_frame_info machinery. This allows us to avoid depending on libgcc_s.so.1 in binaries that do not use exception handling directly. As an additional benefit it breaks circular libc <=> libgcc_s.so.1 dependency too. Build newly added libgomp.so.1 library, the runtime support bits for OpenMP. Build LGPLed libssp library. Our libc provides our own BSD-licensed SSP callbacks implementation, so this library is only built to benefit applications that have hadcoded knowledge of libssp.so and libssp_nonshared.a. When linked in from command line, these libraries override libc implementation. List of files: /freebsd-12.1/gnu/lib/libgomp/Makefile
