From 9c74856af78ac3e8aaa5f8b560e5022d2e6037d1 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 4 Oct 2012 22:48:33 -0400 Subject: dynamic-linked TLS support for everything but dlopen'd libs currently, only i386 is tested. x86_64 and arm should probably work. the necessary relocation types for mips and microblaze have not been added because I don't understand how they're supposed to work, and I'm not even sure if it's defined yet on microblaze. I may be able to reverse engineer the requirements out of gcc/binutils output. --- arch/x86_64/reloc.h | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) (limited to 'arch/x86_64') diff --git a/arch/x86_64/reloc.h b/arch/x86_64/reloc.h index b0bbfb3e..a09df337 100644 --- a/arch/x86_64/reloc.h +++ b/arch/x86_64/reloc.h @@ -7,7 +7,11 @@ #define IS_COPY(x) ((x)==R_X86_64_COPY) #define IS_PLT(x) ((x)==R_X86_64_JUMP_SLOT) -static inline void do_single_reloc(size_t *reloc_addr, int type, size_t sym_val, size_t sym_size, unsigned char *base_addr, size_t addend) +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_X86_64_GLOB_DAT: @@ -27,5 +31,16 @@ static inline void do_single_reloc(size_t *reloc_addr, int type, size_t sym_val, case R_X86_64_COPY: memcpy(reloc_addr, (void *)sym_val, sym_size); break; + case R_X86_64_TLS_DTPMOD64: + *reloc_addr = def.dso ? def.dso->tls_id : self->tls_id; + break; + case R_X86_64_TLS_DTPOFF64: + *reloc_addr = def.sym->st_value + addend; + break; + case R_X86_64_TLS_TPOFF64: + *reloc_addr = (def.sym + ? def.sym->st_value - def.dso->tls_offset + : 0 - self->tls_offset) + addend; + break; } } -- cgit v1.2.1
