Andrew Kelley	d917815d81	explicitly return from blocks ... instead of last statement being expression value closes #629	2017-12-22 00:50:30 -05:00
Andrew Kelley	b8ed0cb374	remove workaround for LLVM not respecting "nobuiltin" ... now that we depend on LLVM 5.0.0 we can remove the workaround. closes #393	2017-08-28 04:28:42 -04:00
Andrew Kelley	987768778a	bit shifting safety ... * add u3, u4, u5, u6, u7 and i3, i4, i5, i6, i7 * shift operations shift amount parameter type is integer with log2 bit width of other param - This enforces not violating undefined behavior on shift amount >= bit width with the type system * clean up math.log, math.ln, math.log2, math.log10 closes #403	2017-08-19 01:43:43 -04:00
Marc Tiehuis	5bbec42a4e	Add math special case tests and general fixes ... - Should cover special case inputs for most functions - Fixed a number of runtime panicking behaviour reliant on shift overflow/division by zero etc.	2017-06-20 23:10:22 +12:00
Andrew Kelley	c9fc8bd802	workaround for llvm bug ... See #393 for details	2017-06-19 14:36:33 -04:00
Marc Tiehuis	4c16f9a3c3	Add math library ... This covers the majority of the functions as covered by the C99 specification for a math library. Code is adapted primarily from musl libc, with the pow and standard trigonometric functions adapted from the Go stdlib. Changes: - Remove assert expose in index and import as needed. - Add float log function and merge with existing base 2 integer implementation. See https://github.com/tiehuis/zig-fmath. See #374.	2017-06-16 20:32:31 +12:00
