From aacd348637e38795dd7ae3c7c8c908d8c0cd24fd Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 27 Feb 2014 22:03:25 -0500 Subject: rename superh port to "sh" for consistency linux, gcc, etc. all use "sh" as the name for the superh arch. there was already some inconsistency internally in musl: the dynamic linker was searching for "ld-musl-sh.path" as its path file despite its own name being "ld-musl-superh.so.1". there was some sentiment in both directions as to how to resolve the inconsistency, but overall "sh" was favored. --- arch/sh/reloc.h | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 arch/sh/reloc.h (limited to 'arch/sh/reloc.h') diff --git a/arch/sh/reloc.h b/arch/sh/reloc.h new file mode 100644 index 00000000..97bee6ae --- /dev/null +++ b/arch/sh/reloc.h @@ -0,0 +1,47 @@ +#if __BYTE_ORDER == __LITTLE_ENDIAN +#define ENDIAN_SUFFIX "l" +#else +#define ENDIAN_SUFFIX "" +#endif + +#define LDSO_ARCH "sh" ENDIAN_SUFFIX + +#define IS_COPY(x) ((x) == R_SH_COPY) +#define IS_PLT(x) ((x) == R_SH_JMP_SLOT) + +static inline void do_single_reloc( + struct dso *self, unsigned char *base_addr, + size_t *reloc_addr, int type, size_t addend, + Sym *sym, size_t sym_size, + struct symdef def, size_t sym_val) +{ + switch(type) { + case R_SH_GLOB_DAT: + case R_SH_JMP_SLOT: + *reloc_addr = sym_val; + break; + case R_SH_RELATIVE: + *reloc_addr = (size_t)base_addr + addend; + break; + case R_SH_DIR32: + *reloc_addr = sym_val + addend; + break; + case R_SH_REL32: + *reloc_addr = sym_val + addend - (size_t)reloc_addr + (size_t)base_addr; + break; + case R_SH_COPY: + memcpy(reloc_addr, (void *)sym_val, sym_size); + break; + case R_SH_TLS_DTPMOD32: + *reloc_addr += def.dso ? def.dso->tls_id : self->tls_id; + break; + case R_SH_TLS_DTPOFF32: + *reloc_addr += def.sym->st_value; + break; + case R_SH_TLS_TPOFF32: + *reloc_addr += def.sym + ? def.sym->st_value + def.dso->tls_offset + 8 + : self->tls_offset + 8; + break; + } +} -- cgit v1.2.1
