* Retire obsolete GDB 6.1.1Ed Maste2020-12-153-1898/+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support to LLDB or find another path for crashinfo's needs, but in any case we do not want to ship the excessively outdated GDB in FreeBSD 13.

* Create a new MACHINE_ARCH for Freescale PowerPC e500v2Justin Hibbits2016-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This is an optional coprocessors may not be present in all devices, however it appears to be in all current SoCs we support. armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too old to support this. Because of this there are a number of WITH/WITHOUT options that are unsupported and must be left as the default value. The options and their required value are: * WITH_ARM_EABI * WITHOUT_GCC * WITHOUT_GNUCXX In addition, without an external toolchain, the following need to be left as their default: * WITH_CLANG * WITH_CLANG_IS_CC As there is a different method of passing float and double values to functions the ABI is incompatible with existing armv6 binaries. To use this a full rebuild of world is required. Because no floating point values are passed into the kernel an armv6 kernel with VFP enabled will work with an armv6hf userland and vice versa.

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

In order to do that, and in order to avoid KBI breakage with existing infrastructure the following semantic is implemented: - For live programs, a new member to the PT_LWPINFO is added (pl_tdname) - For cores, a new ELF note is added (NT_THRMISC) that can be used for storing thread specific, miscellaneous, informations. Right now it is just popluated with a thread name. GDB, then, retrieves the correct informations from the corefile via the BFD interface, as it groks the ELF notes and create appropriate pseudo-sections.

| | | | | | | | | | | | | | | | | | ABI change on ILP32 platforms and relating to events. However it's harmless on little-endian ILP32 platforms in the sense that it doesn't cause breakages. Old ILP32 thread libraries write a 32-bit th_p and new thread libraries write a 64-bit th_p. But due to the fact that we have an unused 32-bit data field right after th_p and that field is always initialized to zero, little-endian ILP32 machines effectively have a valid 64-bit th_p by accident. Likewise for new thread libraries and old libthread_db: little endian ILP32 is unaffected. At this time we don't support big-endian threaded applications in GDB, so the breakage for the ILP32 case goes unnoticed. Notes: svn path=/head/; revision=183023

| | | | | | | | | | | | | | | | | | | | list of frame sniffers so that trapframes can be detected. The kluge is needed because this version of gdb only supports appending a sniffer to the list of sniffers and the moment kgdb gets a chance to add its own frame sniffer, the target's default frame sniffer is already in the list. Since the default frame sniffer claims any frame thrown at it, kgdb's frame sniffer never gets to smell (a process much akin to tasting, but with lesser chance of hurling :-) This commit adds dummy frame sniffers that never claim a frame and as such don't fix anything yet. However, we now have frame sniffers and they are being called, so it's just a matter of adding meat to the bones and we'll be able to properly unwind across trapframes.
