From c2e843276310bfa2eb0fa40c6b54f530ac207a4f Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Tue, 24 Jan 2017 17:07:36 +0000 Subject: Add "__RTL" to cc1 gcc/c-family/ChangeLog: * c-common.c (c_common_reswords): Add "__RTL". * c-common.h (enum rid): Add RID_RTL. gcc/c/ChangeLog: * c-parser.c: Include "read-rtl-function.h" and "run-rtl-passes.h". (c_parser_declaration_or_fndef): Rename "gimple-pass-list" in grammar to gimple-or-rtl-pass-list. Add rtl-function-definition production. Update for renaming of field "gimple_pass" to "gimple_or_rtl_pass". If __RTL was seen, call c_parser_parse_rtl_body. Convert a timevar_push/pop pair to an auto_timevar, to cope with early exit. (c_parser_declspecs): Update RID_GIMPLE handling for renaming of field "gimple_pass" to "gimple_or_rtl_pass", and for renaming of c_parser_gimple_pass_list to c_parser_gimple_or_rtl_pass_list. Handle RID_RTL. (c_parser_parse_rtl_body): New function. * c-tree.h (enum c_declspec_word): Add cdw_rtl. (struct c_declspecs): Rename field "gimple_pass" to "gimple_or_rtl_pass". Add field "rtl_p". * gimple-parser.c (c_parser_gimple_pass_list): Rename to... (c_parser_gimple_or_rtl_pass_list): ...this, updating accordingly. * gimple-parser.h (c_parser_gimple_pass_list): Rename to... (c_parser_gimple_or_rtl_pass_list): ...this. gcc/ChangeLog: * cfg.c (original_copy_tables_initialized_p): New function. * cfg.h (original_copy_tables_initialized_p): New decl. * cfgrtl.c (relink_block_chain): Guard the call to free_original_copy_tables with a call to original_copy_tables_initialized_p. * cgraph.h (symtab_node::native_rtl_p): New decl. * cgraphunit.c (symtab_node::native_rtl_p): New function. (symtab_node::needed_p): Don't assert for early assembly output for __RTL functions. (cgraph_node::finalize_function): Set "force_output" for __RTL functions. (cgraph_node::analyze): Bail out early for __RTL functions. (analyze_functions): Update assertion to support __RTL functions. (cgraph_node::expand): Bail out early for __RTL functions. * final.c (rest_of_clean_state): Don't call delete_tree_ssa for __RTL functions. * function.h (struct function): Update comment for field "pass_startwith". * gimple-expr.c: Include "tree-pass.h". (gimple_has_body_p): Return false for __RTL functions. * Makefile.in (OBJS): Add run-rtl-passes.o. * pass_manager.h (gcc::pass_manager::get_rest_of_compilation): New accessor. (gcc::pass_manager::get_clean_slate): New accessor. * passes.c: Include "insn-addr.h". (should_skip_pass_p): Add logging. Update logic for running "expand" to be compatible with both __GIMPLE and __RTL. Guard property-provider override so it is only done for gimple passes. Don't skip dfinit. (skip_pass): New function. (execute_one_pass): Call skip_pass when skipping passes. * read-md.c (md_reader::read_char): Support filtering the input to a subset of line numbers. (md_reader::md_reader): Initialize fields m_first_line and m_last_line. (md_reader::read_file_fragment): New function. * read-md.h (md_reader::read_file_fragment): New decl. (md_reader::m_first_line): New field. (md_reader::m_last_line): New field. * read-rtl-function.c (function_reader::create_function): Only create cfun if it doesn't already exist. Set PROP_rtl on cfun's curr_properties. Set DECL_INITIAL to a dummy block. (read_rtl_function_body_from_file_range): New function. * read-rtl-function.h (read_rtl_function_body_from_file_range): New decl. * run-rtl-passes.c: New file. * run-rtl-passes.h: New file. gcc/testsuite/ChangeLog: * gcc.dg/rtl/aarch64/asr_div1.c: New test case. * gcc.dg/rtl/aarch64/pr71779.c: New test case. * gcc.dg/rtl/rtl.exp: New file. * gcc.dg/rtl/test.c: New file. * gcc.dg/rtl/truncated-rtl-file.c: New test case. * gcc.dg/rtl/unknown-rtx-code.c: New test case. * gcc.dg/rtl/x86_64/dfinit.c: New test case. * gcc.dg/rtl/x86_64/different-structs.c: New test case. * gcc.dg/rtl/x86_64/final.c: New test case. * gcc.dg/rtl/x86_64/into-cfglayout.c: New test case. * gcc.dg/rtl/x86_64/ira.c: New test case. * gcc.dg/rtl/x86_64/pro_and_epilogue.c: New test case. * gcc.dg/rtl/x86_64/test-multiple-fns.c: New test case. * gcc.dg/rtl/x86_64/test-return-const.c.after-expand.c: New test case. * gcc.dg/rtl/x86_64/test-return-const.c.before-fwprop.c: New test case. * gcc.dg/rtl/x86_64/test-rtl.c: New test case. * gcc.dg/rtl/x86_64/test_1.h: New file. * gcc.dg/rtl/x86_64/times-two.c.after-expand.c: New test case. * gcc.dg/rtl/x86_64/times-two.c.before-df.c: New test case. * gcc.dg/rtl/x86_64/times-two.h: New file. * gcc.dg/rtl/x86_64/vregs.c: New test case.
