| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Author: Alex Suykov <alex.suykov@gmail.com> Author: Aric Belsito <lluixhi@gmail.com> Author: Drew DeVault <sir@cmpwn.com> Author: Michael Clark <mjc@sifive.com> Author: Michael Forney <mforney@mforney.org> Author: Stefan O'Rear <sorear2@gmail.com> This port has involved the work of many people over several years. I have tried to ensure that everyone with substantial contributions has been credited above; if any omissions are found they will be noted later in an update to the authors/contributors list in the COPYRIGHT file. The version committed here comes from the riscv/riscv-musl repo's commit 3fe7e2c75df78eef42dcdc352a55757729f451e2, with minor changes by me for issues found during final review: - a_ll/a_sc atomics are removed (according to the ISA spec, lr/sc are not safe to use in separate inline asm fragments) - a_cas[_p] is fixed to be a memory barrier - the call from the _start assembly into the C part of crt1/ldso is changed to allow for the possibility that the linker does not place them nearby each other. - DTP_OFFSET is defined correctly so that local-dynamic TLS works - reloc.h LDSO_ARCH logic is simplified and made explicit. - unused, non-functional crti/n asm files are removed. - an empty .sdata section is added to crt1 so that the __global_pointer reference is resolvable. - indentation style errors in some asm files are fixed.

| | | | | | | | sync with gabi: http://www.sco.com/developers/gabi/latest/ch4.eheader.html EM_BPF is new in linux v4.8 and officially assigned: https://lists.iovisor.org/pipermail/iovisor-dev/2016-June/000266.html added related relocs too.
* make brace placement in public header typedef'd structs consistentRich Felker2016-07-031-12/+6
| | | | | | commit befa5866ee30d09c0c96e88af2eabff5911342ea performed this change for struct definitions that did not also involve typedef, but omitted the latter.
* add EF_SH_ sh specific macros to elf.hSzabolcs Nagy2016-07-031-1/+22
| | | | | last time elf.h was thoroughly updated sh was not yet supported so these processor specific e_flags were missing.

* add new powerpc64 relocations to elf.hSzabolcs Nagy2016-07-031-0/+9
| | | | | following the corresponding binutils and glibc changes https://sourceware.org/ml/binutils/2013-10/msg00372.html
* add EM_OPENRISC again to elf.hSzabolcs Nagy2016-07-031-0/+1
| | | | | | | | | it was changed to EM_OR1K in 200d15479c0bc48471ee7b8e538ce33af990f82e as that was meant to be the official name, but glibc and the latest gabi spec still uses the EM_OPENRISC name: http://www.sco.com/developers/gabi/latest/ch4.eheader.html binutils defines both macros so we should do the same for backward compatibility.
* add sh relocation types needed for fdpic to elf.hRich Felker2015-09-121-0/+8

* fix integer overflow in elf.h macro SHF_EXCLUDERich Felker2015-05-011-1/+1
|
* add or1k (OpenRISC 1000) architecture portStefan Kristiansson2014-07-181-1/+37
| | | | | | | | | | | | | | | With the exception of a fenv implementation, the port is fully featured. The port has been tested in or1ksim, the golden reference functional simulator for OpenRISC 1000. It passes all libc-test tests (except the math tests that requires a fenv implementation). The port assumes an or1k implementation that has support for atomic instructions (l.lwa/l.swa). Although it passes all the libc-test tests, the port is still in an experimental state, and has yet experienced very little 'real-world' use.

* microblaze portRich Felker2012-09-291-0/+24
| | | | | | based on initial work by rdp, with heavy modifications. some features including threads are untested because qemu app-level emulation seems to be broken and I do not have a proper system image for testing.
* header file fixes: multiple include guard consistency and correctnessRich Felker2012-06-151-1/+1
| | | | | | | one file was reusing another file's macro name, and many had inconsistent underscores and application of SYS prefix, etc. patch by Szabolcs Nagy (nsz)
