Compiler-generated - code calls mcount after executing a function's prologue, placing - the "lr" register in "r10" for the call. As a result "lr" is the - function that invoked mcount, and "r10" is mcount's caller's - caller. However, we have to save all the parameter registers here - before invoking _mcount_internal. Callee-save and temporary - registers need no special attention. We save r10 and restore it to - lr on the way out, to properly handle the case of ENTRY() in - assembly code, before lr is saved. We use the name __mcount since - the gcc community prefers using the reserved namespace. */ - -#include <sysdep.h> - - .text -ENTRY(__mcount) - { - ST sp, lr - ADDI_PTR r29, sp, - (12 * REGSIZE) - } - cfi_offset (lr, 0) - { - ADDI_PTR sp, sp, - (13 * REGSIZE) - ST r29, sp - ADDI_PTR r29, r29, REGSIZE - } - cfi_def_cfa_offset (13 * REGSIZE) - { ST r29, r0; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r1; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r2; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r3; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r4; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r5; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r6; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r7; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r8; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r9; ADDI_PTR r29, r29, REGSIZE } - { ST r29, r10; ADDI_PTR r29, r29, REGSIZE; move r0, r10 } - { - move r1, lr - jal __mcount_internal - } - { - ADDI_PTR r29, sp, (2 * REGSIZE) - } - { LD r0, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r1, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r2, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r3, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r4, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r5, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r6, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r7, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r8, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r9, r29; ADDI_PTR r29, r29, REGSIZE } - { LD r10, r29; ADDI_PTR sp, sp, (13 * REGSIZE) } - cfi_def_cfa_offset (0) - { - LD lr, sp - } - { - move lr, r10 - jrp lr - } -END(__mcount) - -#undef mcount -weak_alias (__mcount, _mcount) /* exported in gmon/Versions */ -weak_alias (__mcount, mcount) /* exported in stdlib/Versions */ |
