40dbcd09da fix type_is_codegen_pointer being used incorrectly 
The names of these functions should probably change, but at least
the semantics are correct now:
 * type_is_codegen_pointer - the type is either a fn, ptr, or promise
 * get_codegen_ptr_type -
   - ?&T and &T returns &T
   - ?promise and promise returns promise
   - ?fn()void and fn()void returns fn()void
   - otherwise returns nullptr

02f70cda8a zig_llvm.cpp uses new(std::nothrow) 
This fixes a mismatched malloc/delete because
we were allocating with malloc and then llvm was
freeing with delete.

ec0846a00f std.heap.ArenaAllocator: fix incorrectly activating safety check 2018-02-12 03:21:18 -05:00
Andrew Kelley
227ead54be back to malloc instead of aligned_alloc for c_allocator 
it seems that a 7 years old standard is still too new for the
libc variants that are ubiquitous

(tests failing on macos for not providing C11 ABI)

4a4ea92cf3 remove std.heap.IncrementingAllocator 
Use std.heap.FixedBufferAllocator combined with
std.heap.DirectAllocator instead.

std.mem.FixedBufferAllocator is moved to std.heap.FixedBufferAllocator

445b03384a introduce std.heap.ArenaAllocator and std.heap.DirectAllocator 
* DirectAllocator does the underlying syscall for every allocation.
 * ArenaAllocator takes another allocator as an argument and
   allocates bytes up front, falling back to DirectAllocator with
   increasingly large allocation sizes, to avoid calling it too often.
   Then the entire arena can be freed at once.

The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.

docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.

The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.

Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.

Fixed a bug in Allocator when you call realloc to grow the allocation.
