PR gold/18048: Fix INCLUDE directive support for gold
This patch fixes INCLUDE directives in script files, so that when an INCLUDE appears inside a sections block, section commands block, or memory def block, the contents are parsed in the appropriate context. gold/ PR gold/18048 * script-c.h (script_include_directive): Add first_token parameter. * script.cc (script_include_directive): Add first_token parameter, and pass it to read_script_file. * yyscript.y (PARSING_SECTIONS_BLOCK, PARSING_SECTION_CMDS) (PARSING_MEMORY_DEF): New tokens. (top): Add new productions for INCLUDE files. (file_cmd): Replace file_or_sections_cmd with copy of its productions. Pass PARSING_LINKER_SCRIPT to script_include_directive. (section_block_cmd): Likewise; pass PARSING_SECTIONS_BLOCK. (section_cmd): Pass PARSING_SECTION_CMDS. (file_or_sections_cmd): Remove. (memory_def): Pass PARSING_MEMORY_DEF. * testsuite/Makefile.am (memory_test_2): New test. * testsuite/Makefile.in: Regenerate. * testsuite/memory_test_inc.t: New script file. * testsuite/memory_test_inc_1.t.src: New script file. * testsuite/memory_test_inc_2.t.src: New script file. * testsuite/memory_test_inc_3.t.src: New script file.
