From 7cf3f604fb102ba67ce3abe7e97440b4ed0da92e Mon Sep 17 00:00:00 2001 From: Nathan Sidwell Date: Tue, 19 May 2020 13:20:32 -0700 Subject: [PATCH] preprocessor: Random cleanups This fixes a bunch of poorly formatted decls, marks some getters as PURE, deletes some C-relevant bool hackery, and finally uses a passed-in location rather than deducing a closely-related but not necessarily the same location. * include/cpplib.h (cpp_get_otions, cpp_get_callbacks) (cpp_get_deps): Mark as PURE. * include/line-map.h (get_combined_adhoc_loc) (get_location_from_adhoc_loc, get_pure_location): Reformat decls. * internal.h (struct lexer_state): Clarify comment. * system.h: Remove now-unneeded bool hackery. * files.c (_cpp_find_file): Store LOC not highest_location. --- libcpp/ChangeLog | 8 ++++++++ libcpp/files.c | 6 +++--- libcpp/include/cpplib.h | 6 +++--- libcpp/include/line-map.h | 11 ++++------- libcpp/internal.h | 2 +- libcpp/system.h | 20 -------------------- 6 files changed, 19 insertions(+), 34 deletions(-) diff --git a/libcpp/ChangeLog b/libcpp/ChangeLog index 5bfa184..040de52 100644 --- a/libcpp/ChangeLog +++ b/libcpp/ChangeLog @@ -1,5 +1,13 @@ 2020-05-18 Nathan Sidwell + * include/cpplib.h (cpp_get_otions, cpp_get_callbacks) + (cpp_get_deps): Mark as PURE. + * include/line-map.h (get_combined_adhoc_loc) + (get_location_from_adhoc_loc, get_pure_location): Reformat decls. + * internal.h (struct lexer_state): Clarify comment. + * system.h: Remove now-unneeded bool hackery. + * files.c (_cpp_find_file): Store LOC not highest_location. + PR preprocessor/95149 * lex.c (struct lit_accum): New.
