From 9cba52f0aedbb95671e8a14e3fd5ff98381ff2b0 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Thu, 8 Aug 2002 14:35:49 +0000 Subject: Patch from Stefan Allius and Edie C. Dost to add SuperH shared library support. This also adds some cleaner error handling, which I (Erik) then ported over to x86 and arm. In addition Stefan added the following fixes: - in hash.c was the lvalue handling of global library functions wrong. To fix this I had to change the prototype of _dl_find_hash. (==> TIS and ELF spec. Vers. 1.2) - in ldso.c was the order of the .init sections calls wrong. Before we call the initialization code of a library we have to check that all dependend libraries are already initialized. This can easily made by calling it in the revers loading order. For this I added a previous pointer chain. - in ldso.c the ELF magics wasn't checked fo PPC, MIPS and SH architecture --- ldso/ldso/sh/boot1_arch.h | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 ldso/ldso/sh/boot1_arch.h (limited to 'ldso/ldso/sh/boot1_arch.h') diff --git a/ldso/ldso/sh/boot1_arch.h b/ldso/ldso/sh/boot1_arch.h new file mode 100644 index 000000000..798121dc0 --- /dev/null +++ b/ldso/ldso/sh/boot1_arch.h @@ -0,0 +1,23 @@ +/* Any assmbly language/system dependent hacks needed to setup boot1.c so it + * will work as expected and cope with whatever platform specific wierdness is + * needed for this architecture. */ + +asm("\ + .text + .globl _dl_boot +_dl_boot: + mov r15, r4 + mov.l .L_dl_boot2, r1 + mova .L_dl_boot2, r0 + add r1, r0 + jsr @r0 + add #4, r4 + jmp @r0 + mov #0, r4 /* call _start with arg == 0 */ +.L_dl_boot2:\n\ + .long _dl_boot2-.\n\ + .previous\n\ +"); + +#define _dl_boot _dl_boot2 +#define LD_BOOT(X) static void * __attribute__ ((unused)) _dl_boot (X) -- cgit v1.2.3
