From f8a57be8182804460dde7e7f28a681e26577fdae Mon Sep 17 00:00:00 2001 From: Geoffrey Keating Date: Thu, 1 Jul 2004 04:09:07 +0000 Subject: Index: gcc/ChangeLog 2004-06-28 Geoffrey Keating Andreas Tobler PR 15813 * dwarf2out.c (reg_save): Output DW_CFA_same_value when a register is saved in itself. (initial_return_save): If the return address is a register, it's already there, don't bother to mention it in the CFI. (struct queued_reg_save): Add field saved_reg. (struct reg_saved_in_data): New. (regs_saved_in_regs): New. (num_regs_saved_in_regs): New. (queue_reg_save): Add extra parameter to specify register saved in register. Remove duplicate entries from queue. Add comment for function. (flush_queued_reg_saves): Handle registers saved in registers. Update regs_saved_in_regs. Add comment for function. (clobbers_queued_reg_save): Add comment for function. Allow for regs_saved_in_regs. (reg_saved_in): New. (dwarf2out_frame_debug_expr): Handle saving registers in other registers. (dwarf2out_frame_debug): Reset regs_saved_in_regs. * unwind-dw2.c (execute_cfa_program): Correct handling of DW_CFA_same_value. Add FIXME comment about incorrect implementation of DW_CFA_restore_extended. * config/rs6000/rs6000.c (rs6000_emit_prologue): Let dwarf2out_frame_debug_expr see instructions that save registers in other registers or save those other registers in memory. * unwind-dw2.c (DWARF_FRAME_REGISTERS): Move to unwind-dw2.h. (_Unwind_FrameState): Likewise. * unwind-dw2.h: New. * Makefile.in (LIB2ADDEHDEP): Add unwind-dw2.h. * config/rs6000/darwin-fallback.c: New file. * config/rs6000/darwin.h (MD_FALLBACK_FRAME_STATE_FOR): Define. * config/rs6000/t-darwin (LIB2FUNCS_EXTRA): Add darwin-fallback.o. Index: gcc/testsuite/ChangeLog 2004-06-26 Geoffrey Keating Andreas Tobler * gcc.dg/cleanup-10.c: Run on all Linux platforms and powerpc-darwin. Use SA_RESETHAND rather than SA_ONESHOT. Trap SIGBUS as well as SIGSEGV. * gcc.dg/cleanup-11.c: Likewise. * gcc.dg/cleanup-8.c: Likewise. * gcc.dg/cleanup-9.c: Likewise. * gcc.dg/cleanup-5.c: Run on all platforms. Index: libjava/ChangeLog 2004-06-26 Geoffrey Keating Andreas Tobler * configure.host (powerpc-*-darwin*): New case, define can_unwind_signal. * configure.in (*-*-darwin*): New case, point to darwin-signal.h. * configure: Regenerate. * include/darwin-signal.h: New.
