gcc/ PR target/34981 * config/mips/mips-protos.h (mips_expand_call): Return an rtx. * config/mips/mips.h (FIRST_PSEUDO_REGISTER): Rename FAKE_CALL_REGNO to GOT_VERSION_REGNUM. (CALL_REALLY_USED_REGISTERS): Set the GOT_VERSION_REGNUM entry to 0. (EPILOGUE_USES): Include GOT_VERSION_REGNUM if TARGET_USE_GOT. * config/mips/mips.c (mips_emit_call_insn): New function. (mips_call_tls_get_addr): Call mips_expand_call directly. (mips16_copy_fpr_return_value): Use mips_emit_call_insn rather than emit_call_insn. (mips16_build_call_stub): Likewise. Return the call insn or null. (mips_expand_call): Update the call to mips16_build_call_stub accordingly and a remove redundant condition. Assert that MIPS16 stubs do not use lazy binding. Use mips_emit_call_insn and return the call insn. (mips_extra_live_on_entry): Include GOT_VERSION_REGNUM if TARGET_USE_GOT. (mips_hard_regno_mode_ok_p): Allow SImode for GOT_VERSION_REGNUM. (mips_avoid_hazard): Remove hazard_set handling. * config/mips/mips.md (UNSPEC_EH_RECEIVER): Rename to... (UNSPEC_RESTORE_GP): ...this. (UNSPEC_SET_GOT_VERSION, UNSPEC_UPDATE_GOT_VERSION): New constants. (FAKE_CALL_REGNO): Rename to... (GOT_VERSION_REGNUM): ...this. (type): Add "ghost" value. Add an associated insn reservation. (hazard_set): Remove. (exception_receiver): Rename to... (restore_gp): ...this and update the unspec identifier accordingly. (exception_receiver, nonlocal_got_receiver): New expanders. (load_call<mode>): Use GOT_VERSION_REGNUM. Don't set FAKE_CALL_REGNO. Remove hazard_set attribute. (set_got_version, update_got_version): New patterns. gcc/testsuite/ PR target/34981 * gcc.target/mips/lazy-binding-1.c: New test. * gcc.target/mips/mips.exp (setup_mips_tests): Set mips_forced_no_abicalls and mips_forced_no_shared. (dg-mips-options): Avoid using -mabicalls with an implicit -mabi=eabi. Avoid using small data with -mabicalls. Don't make -G0 force -mn-abicalls. Skip -mabicalls and -mshared tests if the multilib forces the opposite option. From-SVN: r131860 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
