<stdint.h> includes. (#150303)
https://github.com/llvm/llvm-project/issues/149993
|
|
Summary:
This patch uses the actual allocator interface to implement
`aligned_alloc`. We do this by simply rounding up the amount allocated.
Because of how index calculation works, any offset within an allocated
pointer will still map to the same chunk, so we can just adjust
internally and it will free all the same.
|
|
Summary:
Now that we have `malloc` we can implement `realloc` efficiently. This
uses the known chunk sizes to avoid unnecessary allocations. We just
return nullptr for NVPTX. I'd remove the list for the entrypoint but
then the libc++ code would stop working. When someone writes the NVPTX
support this will be trivial.

|
Summary:
This is a NFC move preceding more radical functional changes to the
allocator implementation. We just move it to a common utility so it will
be easier to write these in tandem.
