From d3331fba6eaab44646010b556106da38925d43e0 Mon Sep 17 00:00:00 2001 From: jsmall-nvidia Date: Thu, 6 Feb 2020 14:31:09 -0500 Subject: Literal handling improvements (#1202) * WIP: 64 literal diagnostic and truncation. * Improve how integer truncation is handled/supported. Added literal-int64.slang test. Set a suffix on all literals. Fixed problem on C++ based targets where l suffix was not the same as int() cast. So on C++ derived emitters, int() is used instead of l suffix to have same behavior across targets. * Add literal diagnostic testing. * Allow lexer to lex - in front of literals. * Fix lexing and converting int literal with -. * Too large small values of floats become inf. Handling writing inf types out on different targets. Add function to deterimine if a float literals kind. * Roll back the support of lexer lexing negative literals. * Fixed tests broken because of diagnostics numbers. Improved _isFinite * Fix compilation on linux. * Fix problem with abs on linux - use Math::Abs. * Fix typo. * * Improve warnings for float literals zeroed * Improved 64 bit type documentation * Handle half * Improved comments * Fixed tests broken * Use capital letters for suffixes. * Make default behavior on outputting a int literal that is an 'int32_t' is cast (not suffix) to avoid platform inconsistencies. Improve documentation for 64 bit types. Make tests cover material in docs. * Fixed tests. * Rename FloatKind::Normal -> Finite * Fix half zero check. --- tests/diagnostics/float-literal.slang.expected | 9 +++++++++ 1 file changed, 9 insertions(+) create mode 100644 tests/diagnostics/float-literal.slang.expected (limited to 'tests/diagnostics/float-literal.slang.expected') diff --git a/tests/diagnostics/float-literal.slang.expected b/tests/diagnostics/float-literal.slang.expected new file mode 100644 index 000000000..347317666 --- /dev/null +++ b/tests/diagnostics/float-literal.slang.expected @@ -0,0 +1,9 @@ +result code = 0 +standard error = { +tests/diagnostics/float-literal.slang(7): warning 39999: float literal '5e+40' unrepresentable, converted to 'inf' +tests/diagnostics/float-literal.slang(9): warning 39999: '9e-50' is smaller than the smallest representable value for type float, converted to '0' +tests/diagnostics/float-literal.slang(19): warning 39999: float literal '5e+40' unrepresentable, converted to 'inf' +tests/diagnostics/float-literal.slang(20): warning 39999: '9e-50' is smaller than the smallest representable value for type float, converted to '0' +} +standard output = { +} -- cgit v1.2.3
