hryx 5765cbd2de Allow tag expr for enum but not struct 2019-04-22 00:14:51 -07:00
Andrew Kelley 5eaead6a56 implement allowzero pointer attribute
closes #1953

only needed for freestanding targets.

also adds safety for `@intToPtr` when the address is zero.

Andrew Kelley 15c316b0d8 add docs for assembly and fix global assembly parsing
Previously, global assembly was parsed expecting it to have
the template syntax. However global assembly has no inputs,
outputs, or clobbers, and thus does not have template syntax.
This is now fixed.

This commit also adds a compile error for using volatile
on global assembly, since it is meaningless.

closes #1515

Andrew Kelley 581edd643f backport copy elision changes
This commit contains everything from the copy-elision-2
branch that does not have to do with copy elision directly,
but is generally useful for master branch.

 * All const values know their parents, when applicable, not
   just structs and unions.
 * Null pointers in const values are represented explicitly,
   rather than as a HardCodedAddr value of 0.
 * Rename "maybe" to "optional" in various code locations.
 * Separate DeclVarSrc and DeclVarGen
 * Separate PtrCastSrc and PtrCastGen
 * Separate CmpxchgSrc and CmpxchgGen
 * Represent optional error set as an integer, using the 0 value.
   In a const value, it uses nullptr.
 * Introduce type_has_one_possible_value and use it where applicable.
 * Fix debug builds not setting memory to 0xaa when storing
   undefined.
 * Separate the type of a variable from the const value of a variable.
 * Use copy_const_val where appropriate.
 * Rearrange structs to pack data more efficiently.
 * Move test/cases/* to test/behavior/*
 * Use `std.debug.assertOrPanic` in behavior tests instead of
   `std.debug.assert`.
 * Fix outdated slice syntax in docs.

Andrew Kelley 9c328b4291 simpler implementation of && and || hints
This accomplishes the same goal, but with less changes, so that
I can backport copy elision stuff easier.

Andrew Kelley 96164ce613 disallow single-item pointer indexing
add pointer arithmetic for unknown length pointer
2018-06-04 01:39:57 -04:00
Andrew Kelley f06bce5dda introduce [*] for unknown length pointers
See #770

Currently it does not have any different behavior than `*`
but it is now recommended to use `[*]` for unknown length
pointers to be future-proof.

Instead of [ * ] being separate tokens as the proposal
suggested, this commit implements `[*]` as a single token.
2018-06-02 04:04:23 -04:00
Andrew Kelley fcbb7426fa use * for pointer type instead of &
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'

Andrew Kelley a35b366eb6 [breaking] delete ptr deref prefix op

to be done - all the std lib used by the behavior tests

2018-03-22 16:56:03 -04:00
Andrew Kelley f885a1ab61 change async function call syntax
* instead of `async(allocator) call()`, now it is
   `async<allocator> call()`.
 * Fixes syntax ambiguity when leaving off the allocator
 * Fixes parse failure when call is a field access

This sets a precedent for using `<` to pass arguments
to a keyword. This will affect `enum`, `union`, and
`fn` (see #661)
