From 4ccc1a01e037251a0ddc3dd07dd1a1fb91a8aa16 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sat, 12 Sep 2015 03:18:08 +0000 Subject: add fdpic version of entry point code for sh this version of the entry point is only suitable for static linking in ET_EXEC form. neither dynamic linking nor pie is supported yet. at some point in the future the fdpic and non-fdpic versions of this code may be unified but for now it's easiest to work with them separately. --- arch/sh/crt_arch.h | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/arch/sh/crt_arch.h b/arch/sh/crt_arch.h index f8907108..e9745f9b 100644 --- a/arch/sh/crt_arch.h +++ b/arch/sh/crt_arch.h @@ -1,3 +1,30 @@ +#ifdef __SH_FDPIC__ + +__asm__( +".text \n" +".global " START " \n" +START ": \n" +" mov r8, r4 \n" +" mova 1f, r0 \n" +" mov.l 1f, r5 \n" +" mov.l 1f+4, r6 \n" +" add r0, r5 \n" +" bsr __fdpic_fixup \n" +" add r0, r6 \n" +" mov r0, r12 \n" +" mov r15, r4 \n" +" mov #-16, r0 \n" +" bsr " START "_c \n" +" and r0, r15 \n" +".align 2 \n" +"1: .long __ROFIXUP_LIST__@PCREL \n" +" .long __ROFIXUP_END__@PCREL + 4 \n" +); + +#include "fdpic_crt.h" + +#else + __asm__( ".text \n" ".global " START " \n" @@ -16,6 +43,8 @@ START ": \n" "1: .long _DYNAMIC-. \n" ); +#endif + /* used by gcc for switching the FPU between single and double precision */ #ifdef SHARED __attribute__((__visibility__("hidden"))) -- cgit v1.2.1
