* remove GCC 4.2.1 build infrastructureEd Maste2020-02-291-115/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | As described in Warner's email message[1] to the FreeBSD-arch mailing list we have reached GCC 4.2.1's retirement date. At this time all supported architectures either use in-tree Clang, or rely on external toolchain (i.e., a contemporary GCC version from ports). GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later that year, in r171825. GCC has served us well, but version 4.2.1 is obsolete and not used by default on any architecture in FreeBSD. It does not support modern C and does not support arm64 or RISC-V. Thanks to everyone responsible for maintaining, updating, and testing GCC in the FreeBSD base system over the years. So long, and thanks for all the fish.

* Fix GCC 4.2.1 to honor --sysroot for includes.John Baldwin2018-06-271-0/+1
| | | | | | | | | | | | | | | | | | | - Change the C++ directory entries to honor --sysroot if it is set. - Don't define CROSS_INCLUDE_DIR for the cross compiler. Instead, set TARGET_SYSTEM_ROOT to point to WORLDTMP and always define STANDARD_INCLUDE_DIR. - Change STANDARD_INCLUDE_DIR and the C++ include directories to just start with "/usr" always. The compiler will prepend the sysroot when doing cross-builds. GCC_INCLUDE_DIR (which contains headers that ship with the compiler such as intrinsincs rather than OS-supplied headers) remains hardcoded to look in TOOLS_PREFIX.

* Support armv7 builds for userlandWarner Losh2017-10-051-1/+4
| | | | | | | | | | | | | | | | | | | Make armv7 as a new MACHINE_ARCH. Copy all the places we do armv6 and add armv7 as basically an alias. clang appears to generate code for armv7 by default. armv7 hard float isn't supported by the the in-tree gcc, so it hasn't been updated to have a new default. Support armv7 as a new valid MACHINE_ARCH (and by extension TARGET_ARCH). Add armv7 to the universe build.

As such, it's better to leave them since that further the goal of being able to move directories if watned to in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | r238211: Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb This adds a new TARGET_ARCH for building on ARM processors that support the ARMv6K multiprocessor extensions. In particular, these processors have better support for TLS and mutex operations. This mostly touches a lot of Makefiles to extend existing patterns for inferring CPUARCH from ARCH. It also configures: * GCC to default to arm1176jz-s * GCC to predefine __FreeBSD_ARCH_armv6__ * gas to default to ARM_ARCH_V6K * uname -p to return 'armv6' * make so that MACHINE_ARCH defaults to 'armv6' It also changes a number of headers to use the compiler __ARM_ARCH_XXX__ macros to configure processor-specific support routines.

* Retire TARGET_ABI.Warner Losh2011-01-071-9/+6
| | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=217123
* Complete the integration of tbemd branch into head.Warner Losh2010-11-101-3/+7
| | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=215082

* Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.Juli Mallett2010-06-021-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=208737

* Update bmake glue to build GCC 4.2.Alexander Kabaev2007-05-191-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=169718

Thus `cc1plus' wasn't using the hash.h we generated by cc/cc_tools/Makefile, but rather the one in egcs/gcc/cp/. When I imported contrib/gcc/ I did prune gcc/cp/hash.h. Unfortunately the GCC maintainers weren't smart on their file nameing and there is also a egcs/gcc/hash.h (name overloading does NOT work as well on the filesystem as in C++...). Due to the -I ordering we are were then picking up gcc/hash.h when compiling `cc1plus'. Notes: svn path=/head/; revision=52170
