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. Escape found paths. --- tests/preprocessor/special-macro-redefine-object.slang | 13 +++++++++++++ 1 file changed, 13 insertions(+) create mode 100644 tests/preprocessor/special-macro-redefine-object.slang (limited to 'tests/preprocessor/special-macro-redefine-object.slang') diff --git a/tests/preprocessor/special-macro-redefine-object.slang b/tests/preprocessor/special-macro-redefine-object.slang new file mode 100644 index 000000000..531d56ae7 --- /dev/null +++ b/tests/preprocessor/special-macro-redefine-object.slang @@ -0,0 +1,13 @@ +//DIAGNOSTIC_TEST:SIMPLE:-E + +// +// Check replacing __LINE__ +// + +#define __LINE__ "Hello" + +__LINE__ + +#undef __LINE__ + +__LINE__ -- cgit v1.2.3
