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 8bc523219c add labeled loops, labeled break, labeled continue. remove goto
closes #346
closes #630

regression: translate-c can no longer translate switch statements.
after #629 we can ressurect and modify the code to utilize arbitrarily
returning from blocks.

Andrew Kelley 62c25af802 add higher level arg-parsing API + misc. changes
* add @noInlineCall - see #640
   This fixes a crash in --release-safe and --release-fast modes
   where the optimizer inlines everything into _start and
   clobbers the command line argument data.
   If we were able to verify that the user's code never reads
   command line args, we could leave off this "no inline"
   attribute.
 * add i29 and u29 primitive types. u29 is the type of alignment,
   so it makes sense to be a primitive.
   probably in the future we'll make any `i` or `u` followed by
   digits into a primitive.
 * add `aligned` functions to Allocator interface
 * add `os.argsAlloc` and `os.argsFree` so that you can get
   a `[]const []u8`, do whatever arg parsing you want, and then free
   it. For now this uses the other API under the hood, but it could
   be reimplemented to do a single allocation.
 * add tests to make sure command line argument parsing works.

Andrew Kelley 960914a073 add implicit cast from enum to union

to be of a void field of the union

See #618
2017-12-03 22:36:01 -05:00
Andrew Kelley 0ad1239522 rework enums and unions and their relationship to each other
* @enumTagName renamed to @tagName and it works on enums and
   union-enums
 * Remove the EnumTag type. Now there is only enum and union,
   and the tag type of a union is always an enum.
 * unions support specifying the tag enum type, and they support
   inferring an enum tag type.
 * Enums no longer support field types but they do support
   setting the tag values. Likewise union-enums when inferring
   an enum tag type support setting the tag values.
 * It is now an error for enums and unions to have 0 fields.
 * switch statements support union-enums
