From c776fa113da1f0d0cf83418e8937c0a8a4d83d3e Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Tue, 26 Dec 2017 20:51:24 -0800 Subject: RISC-V: ABI Implementation 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 * 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. --- sysdeps/riscv/gccframe.h | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 sysdeps/riscv/gccframe.h (limited to 'sysdeps/riscv/gccframe.h') diff --git a/sysdeps/riscv/gccframe.h b/sysdeps/riscv/gccframe.h new file mode 100644 index 0000000000..3dc62863af --- /dev/null +++ b/sysdeps/riscv/gccframe.h @@ -0,0 +1,21 @@ +/* Definition of object in frame unwind info.
