| | | | | | | | | | | | | | | | The correct names for R_MIPS_GOT_HI16 and R_MIPS_GOT_LO16 have a _ after GOT. The nonstandard names (R_MIPS_GOTHI16, R_MIPS_GOTLO16) in the FreeBSD elf_common.h header also had incorrect values and were not used in the tree, so just remove them. Add other MIPS relocation types found in FreeBSD/mips64 object files.

We don't (currently) have support for STB_GNU_UNIQUE, but ought to reserve the value in ELFNN_ST_BIND. This will also be used by an upcoming ELF Tool Chain import.

* Speed up symbol lookup for the amd64 kernel modules.Konstantin Belousov2015-04-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Amd64 uses relocatable object files as the modules format. It is good WRT not having unneeded overhead for PIC code, in particular, due to absence of useless GOT and PLT. But the cost is that the module linking process cannot use hash to speed up the symbol lookup, and that each reference to the symbol requiring a relocation, instead of single-place relocation in GOT. Cache the successfull symbol lookup results in the module symbol table, using the newly allocated SHN_FBSD_CACHED value from SHN_LOOS-HIOS range as an indicator. The SHN_FBSD_CACHED together with the non-existent definition of the found symbol are reverted after successfull relocations, which is done under kld_sx lock, so it should not be visible to other consumers of the symbol table.

| | | | | | | | | | | | | | | | | The elftoolchain project includes these additional defines for various userland programs. Given that arch-specific defines are still interesting in the context of userland programs reading or writing ELF metadata, they should be included in top-level ELF headers. Remove duplicate defines from ARM and MIPS elf headers.

* Improve support for XSAVE with debuggers.John Baldwin2014-11-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | - Dump an NT_X86_XSTATE note if XSAVE is in use. This note is designed to match what Linux does in that 1) it dumps the entire XSAVE area including the fxsave state, and 2) it stashes a copy of the current xsave mask in the unused padding between the fxsave state and the xstate header at the same location used by Linux. - Teach readelf() to recognize NT_X86_XSTATE notes. - Change PT_GET/SETXSTATE to take the entire XSAVE state instead of only the extra portion. This avoids having to always make two ptrace() calls to get or set the full XSAVE state. - Add a PT_GET_XSTATE_INFO which returns the length of the current XSTATE save area (so the size of the buffer needed for PT_GETXSTATE) and the current XSAVE mask (%xcr0).

| | | | | | | | | | | | | | | | | | | | | | | thread specific informations. 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.
