* Retire obsolete GDB 6.1.1Ed Maste2020-12-1536-7098/+0
| | | | | | | | | | | | | | | | | | | | | GDB 6.1.1 was released in June 2004 and is long obsolete. It does not support all of the architectures that FreeBSD does, and imposes limitations on the FreeBSD kernel build, such as the continued use of DWARF2 debugging information. It was kept (in /usr/libexec/) only for use by crashinfo(8), which extracts some basic information from a kernel core dump after a crash. Crashinfo already prefers gdb from port/package if installed. Future work may add kernel debug support to LLDB or find another path for crashinfo's needs, but in any case we do not want to ship the excessively outdated GDB in FreeBSD 13.

* binutils: build as with BINUTILS || BINUTILS_BOOTSTRAPEd Maste2020-05-301-2/+3
| | | | | | | | | | | | | | | | | Previously we descended into as only if MK_BINUTILS was true, including during the bootstrap tool phase. BINUTILS is now disabled by default on all archs, and we failed to build it during amd64 bootstrap. Descend into as if either BINUTILS or BINUTILS_BOOTSTRAP is enabled. This is not quite correct: we should either have the test also depend on BOOTSTRAPPING, or set BINUTILS to the value of BINUTILS_BOOTSTRAP during the bootstrap phase. However, this simple change fixes the build and has been tested, and binutils will be removed completely in the near future. Notes: svn path=/head/; revision=361656
* binutils: disconnect objdump from the buildEd Maste2020-05-061-4/+0
| | | | | | | | | | | | | | | | | | | | | The in-tree binutils is old and will not be updated. It does not support all archs supported by FreeBSD, and for the archs it does support not all CPU features are supported. Other tools have migrated to copyfree alternatives. Although llvm-objdump is nearly a drop-in replacement for GNU objdump it is missing a few options and has some differences in output format. For now just remove GNU objdump; ports and developers can use a contemporary, maintained version from ports or packages. We can revisit installing llvm-objdump as objdump in the future.

* Create a new MACHINE_ARCH for Freescale PowerPC e500v2Justin Hibbits2016-10-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ld(1) uses the /usr/libdata/ldscripts when linking. These scripts add in the default search paths of /lib and /usr/lib via 'SEARCH_DIR("DIR")'. These need to be prefixed by '=' so that the --sysroot flag is respected. This is not a problem with buildworld since the TOOLS_PREFIX is baked into the cross-ld. However it is a problem when trying to use ld(1) with --sysroot anywhere else as it ends up still reading /lib and /usr/lib despite --sysroot. The default --sysroot (TARGET_SYSTEM_ROOT) is '/' for /usr/bin/ld. I found this while building with META MODE with uses only --sysroot with /usr/bin/ld, and found that libraries that I had not built in its sysroot directory were leaking in. This didn't happen with ports binutils either. This would also impact external compiler support.
