* riscv: restore ABI compatibility (bug 24484)Andreas Schwab2019-07-041-0/+5
| | | | | The contents of the dynamic section are part of the ABI, thus DL_RO_DYN_SECTION cannot be changed.
* riscv: remove DL_RO_DYN_SECTIONDavid Abdurachmanov2019-04-251-4/+0
| | | | | | | | | | | | | | While working on enabling D front-end (GDC) in GCC we noticed that druntime was segfaulting if it is linked dynamically. This was tracked to DL_RO_DYN_SECTION. DL_RO_DYN_SECTION lines seem to be copied from MIPS file (which is the only user of it), but the comment doesn't apply to RISC-V. There is no such requirement in RISC-V ABI. [BZ#24484] * sysdeps/riscv/ldsodefs.h: Remove DL_RO_DYN_SECTION as it is not required by RISC-V ABI.
* Update copyright dates with scripts/update-copyrights.Joseph Myers2019-01-011-1/+1
| | | | | | | * All files with FSF copyright notices: Update copyright dates using scripts/update-copyrights. * locale/programs/charmap-kw.h: Regenerated. * locale/programs/locfile-kw.h: Likewise.
* RISC-V: ABI ImplementationPalmer Dabbelt2018-01-291-0/+47
This patch contains code that needs to directly know about the RISC-V ABI, which is specified in a work-in-progress psABI document: https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md This is meant to contain all the RISC-V code that needs to explicitly name registers or manage in-memory structure layout. This does not contain any of the Linux-specific code. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/__longjmp.S: New file. * sysdeps/riscv/backtrace.c: Likewise. * sysdeps/riscv/bits/endian.h: Likewise. * sysdeps/riscv/bits/setjmp.h: Likewise. * sysdeps/riscv/bits/wordsize.h: Likewise. * sysdeps/riscv/bsd-_setjmp.c: Likewise. * sysdeps/riscv/bsd-setjmp.c: Likewise. * sysdeps/riscv/dl-trampoline.S: Likewise. * sysdeps/riscv/gccframe.h: Likewise. * sysdeps/riscv/jmpbuf-offsets.h: Likewise. * sysdeps/riscv/jmpbuf-unwind.h: Likewise. * sysdeps/riscv/machine-gmon.h: Likewise. * sysdeps/riscv/memusage.h: Likewise. * sysdeps/riscv/setjmp.S: Likewise. * sysdeps/riscv/sys/asm.h: Likewise. * sysdeps/riscv/tls-macros.h: Likewise.
