From 5fde038b1a6b3c8b335cd5b380c3ee8d15403052 Mon Sep 17 00:00:00 2001 From: jsmall-nvidia Date: Wed, 31 Mar 2021 13:11:49 -0400 Subject: Support for __LINE__ and __FILE__ in preprocessor (#1772) * #include an absolute path didn't work - because paths were taken to always be relative. * First pass support for __LINE__ and __FILE__. * Test include handling with __FILE__ Fix diagnostic compare when input is empty. * Fix some issues in preprocessor handling of special macros like __LINE__ Add a more complex test. * Use CONCAT2 in tests, because preprocessor doesn't quite get parameter expansion correct. * Make __FILE__ and __LINE__ behave more like Clang/Gcc. * A test for preprocessor bug. * Fix __LINE__ and __FILE__ in macro expansion, should be initiating location. * Fix some comments. * Small tidy up around builtin macros. * Small improvements for macro type names.
