The changes are: - - Old ARM ABI targets always use FPA (mixed-endian) byte ordering. EABI - targets always use VFP byte ordering for doubles, which is standard - ieee754 layout. Removing the arm-specific ieee754.h doesn't break FPA; - it was a specialized version of the common header, which handles FPA - but also handles VFP. - - The stack needs to be aligned to eight bytes instead of just four, - including in mmap2 and when shifting _dl_argv. - - We need some markers around _start to indicate end-of-stack for the - unwinder - ARM EABI does not use either SJLJ exceptions or DWARF-2 - exceptions. It uses a table based format which seems to be not - quite completely unlike DWARF-2. - -Do these changes look OK? - --- -Daniel Jacobowitz -CodeSourcery, LLC - -2005-03-22 Daniel Jacobowitz <dan@codesourcery.com> - - * sysdeps/arm/bits/endian.h (__FLOAT_WORD_ORDER): Handle VFP. - * sysdeps/arm/gmp-mparam.h (IEEE_DOUBLE_BIG_ENDIAN, - IEEE_DOUBLE_MIXED_ENDIAN): Handle big-endian and VFP. - * sysdeps/arm/ieee754.h: Remove. - - * sysdeps/arm/dl-machine.h (_dl_start_user): Align the stack to eight - bytes even when shifting arguments. - * sysdeps/arm/dl-sysdep.h: New file. - - * sysdeps/arm/elf/start.S (_start): If not using SJLJ exceptions, include - EABI unwind markers to terminate unwinding. - - * sysdeps/unix/sysv/linux/arm/mmap64.S: Handle big-endian byte ordering - and EABI stack layout. - -Index: glibc/sysdeps/arm/bits/endian.h -=================================================================== ---- glibc.orig/sysdeps/arm/bits/endian.h 2005-03-22 10:26:27.092978200 -0500 -+++ glibc/sysdeps/arm/bits/endian.h 2005-03-22 10:27:39.457490903 -0500 -@@ -9,4 +9,9 @@ - #else - #define __BYTE_ORDER __LITTLE_ENDIAN - #endif -+ -+#ifdef __VFP_FP__ -+#define __FLOAT_WORD_ORDER __BYTE_ORDER -+#else - #define __FLOAT_WORD_ORDER __BIG_ENDIAN -+#endif -Index: glibc/sysdeps/arm/dl-machine.h -=================================================================== ---- glibc.orig/sysdeps/arm/dl-machine.h 2005-03-22 10:26:27.092978200 -0500 -+++ glibc/sysdeps/arm/dl-machine.h 2005-03-22 10:27:39.457490903 -0500 -@@ -156,22 +156,19 @@ _dl_start_user:\n\ - add sl, pc, sl\n\ - .L_GOT_GOT:\n\ - ldr r4, [sl, r4]\n\ -- @ get the original arg count\n\ -- ldr r1, [sp]\n\ - @ save the entry point in another register\n\ - mov r6, r0\n\ -- @ adjust the stack pointer to skip the extra args\n\ -- add sp, sp, r4, lsl #2\n\ -- @ subtract _dl_skip_args from original arg count\n\ -- sub r1, r1, r4\n\ -+ @ get the original arg count\n\ -+ ldr r1, [sp]\n\ - @ get the argv address\n\ - add r2, sp, #4\n\ -- @ store the new argc in the new stack location\n\ -- str r1, [sp]\n\ -+ @ Fix up the stack if necessary.\n\ -+ cmp r4, #0\n\ -+ bne .L_fixup_stack\n\ -+.L_done_fixup:\n\ - @ compute envp\n\ - add r3, r2, r1, lsl #2\n\ - add r3, r3, #4\n\ --\n\ - @ now we call _dl_init\n\ - ldr r0, .L_LOADED\n\ - ldr r0, [sl, r0]\n\ -@@ -182,12 +179,45 @@ _dl_start_user:\n\ - add r0, sl, r0\n\ - @ jump to the user_s entry point\n\ - " BX(r6) "\n\ -+\n\ -+ @ iWMMXt and EABI targets require the stack to be eight byte\n\ -+ @ aligned - shuffle arguments etc.\n\ -+.L_fixup_stack:\n\ -+ @ subtract _dl_skip_args from original arg count\n\ -+ sub r1, r1, r4\n\ -+ @ store the new argc in the new stack location\n\ -+ str r1, [sp]\n\ -+ @ find the first unskipped argument\n\ -+ mov r3, r2\n\ -+ add r4, r2, r4, lsl #2\n\ -+ @ shuffle argv down\n\ -+1: ldr r5, [r4], #4\n\ -+ str r5, [r3], #4\n\ -+ cmp r5, #0\n\ -+ bne 1b\n\ -+ @ shuffle envp down\n\ -+1: ldr r5, [r4], #4\n\ -+ str r5, [r3], #4\n\ -+ cmp r5, #0\n\ -+ bne 1b\n\ -+ @ shuffle auxv down\n\ -+1: ldmia r4!, {r0, r5}\n\ -+ stmia r3!, {r0, r5}\n\ -+ cmp r0, #0\n\ -+ bne 1b\n\ -+ @ Update _dl_argv\n\ -+ ldr r3, .L_ARGV\n\ -+ str r2, [sl, r3]\n\ -+ b .L_done_fixup\n\ -+\n\ - .L_GET_GOT:\n\ - .word _GLOBAL_OFFSET_TABLE_ - .L_GOT_GOT - 4\n\ - .L_SKIP_ARGS:\n\ - .word _dl_skip_args(GOTOFF)\n\ - .L_FINI_PROC:\n\ - .word _dl_fini(GOTOFF)\n\ -+.L_ARGV:\n\ -+ .word _dl_argv(GOTOFF)\n\ - .L_LOADED:\n\ - .word _rtld_local(GOTOFF)\n\ - .previous\n\ -Index: glibc/sysdeps/arm/dl-sysdep.h -=================================================================== ---- /dev/null 1970-01-01 00:00:00.000000000 +0000 -+++ glibc/sysdeps/arm/dl-sysdep.h 2005-03-22 10:27:39.458490675 -0500 -@@ -0,0 +1,41 @@ -+/* System-specific settings for dynamic linker code.
