| 2025-06-30 | [libc] Efficiently implement 'realloc' for AMDGPU devices (#145960) | Joseph Huber | |
| 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. | |||
| 2024-07-30 | [libc] Implement placeholder memory functions on the GPU (#101082) | Joseph Huber | |
| Summary: These functions are needed for `libc++` to link successfully. We can't implement them well currently, so simply provide some stand-in implementations. `realloc` will currently copy garbage and potentially fault and `aligned_alloc` will work unless your alignment is more than 4K alignment. However, these should work in practice to get tests running. I will write a real allocator soon™. | |||
