Non-GCC gcc compatible compilers may provide the same multimedia intrinsic headers as GCC, but of their own implementation. So put the GCC ones into their own header "namespace". Requested by: ed

Remove libc, librtld_db, libthr packages, and further increase the constraints on what needs to be installed in a specific to maintain consistency during upgrades. Create a new clibs package containing libraries that are needed as a bare minimum for consistency. With much help and input from: kib Sponsored by: The FreeBSD Foundation

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.

Second attempt at eliminating .text relocations in shared libraries compiled with stack protector. Use libssp_nonshared library to pull __stack_chk_fail_local symbol into each library that needs it instead of pulling it from libc. GCC generates local calls to this function which result in absolute relocations put into position-independent code segment, making dynamic loader do extra work every time given shared library is being relocated and making affected text pages non-shareable.

Man the lifeboats! Tie down the hatches! Red alert! Activate gcc-2.7.2.1! (the old cc has been tagged with "gcc_2_6_3_final" so we have a reference point in case of unforseen disasters...) This has the objc backend active, and I think I've managed to get the f77 f2c support through in one piece, but I don't know fortran to test it. A 'make world' change and libobjc commit will follow. If you normally do 'make -DNOCLEAN world', do not do so this time, I know it can fail with groff. This version of gcc makes a **LOT** more warnings on our kernel.

Working changes for GCC 3.0.2. We now fake out the native libgcc.mk + GNU autoconf'ed Makefile. This gives us the flexability we will need to support our new arches (StrongARM, Sparc64, PowerPC, and IA-64).

Retire TARGET_ABI. Implement MACHINE_ARCH=mips64e[lb] to build N64 images. This replaces MACHINE_ARCH=mipse[lb] TARGET_ABI=n64. MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires WITHOUT_CDDL due to atomic issues in libzfs. I've not investigated this much, but implemented this to preserve as much of the TARGET_ABI functionality that I could. Since its presence doesn't affect the working 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.

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

Create a new MACHINE_ARCH for Freescale PowerPC e500v2 Summary: The Freescale e500v2 PowerPC core does not use a standard FPU. Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor unit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with the stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this. Additionaly, the SPE opcodes overlap with Altivec, so these are mutually exclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, was created with the same function set as in powerpc/powerpc/altivec.c, so it becomes effectively a drop-in replacement. setjmp/longjmp were modified to save the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by the SPE). Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not support double-precision floating point. Also, without a new MACHINE_ARCH it would be impossible to provide binary packages 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 support has been refactored which would make adding a powerpcspe-freebsd target very easy. 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 boot multiuser.

Update for GCC 3.1. Tested on: alpha, sparc64, i386
2002-05-07 00:55:51 +00:00
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.

Complete the integration of tbemd branch into head. TARGET_BIG_ENDIAN is now completely dead, except where it was originally supposed to be used (internally in the toolchain building). TARGET_ARCH has changed in three cases: (1) Little endian mips has changed to mipsel. (2) Big endian mips has changed to mipseb. (3) Big endian arm has changed to armeb. Some additional changes are needed to make 'make universe' work on arm and mips after this change, so those are commented out for now. UPDATING information will be forthcoming. Any remaining rough edges will be hammered out in -current.

Remove MK_ARM_EABI, the armeb issues have been fixed. The code to support the oabi is still in the tree, but it is expected this will be removed as developers work on surrounding code. With this commit the ARM EABI is the only supported supported ABI by FreeBSD on ARMa 32-bit processors. X-MFC after: never Relnotes: yes Differential Revision: https://reviews.freebsd.org/D876

.if ${TARGET_CPUARCH} == "arm"
Add compiler support for the ARM EABI. ARM EABI support is disabled by default and can be enabled by setting WITH_ARM_EABI when building, however only the kernel-toolchain target will work with this flag until the rest of the support is added.

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.
