 [libc][GPU] clean up includes (#143203) 2025-06-06T21:12:07+00:00 Michael Jones michaelrj@google.com 2025-06-06T21:12:07+00:00 3695d6cdf98c252af4a747af8e247b48e046721a The GPU stdio functions were depending on indirect inclusion for some of their dependencies. This patch should fix all of that.

 [libc] Fix leftover `LIBC_NAMESPACE` after porting it (#113960) 2024-10-28T20:47:31+00:00 Joseph Huber huberjn@outlook.com 2024-10-28T20:47:31+00:00 03dcefe08ecb68a3fedb7e9de6277df77371e9fc Summary: There are a few of these leftover, they should all use the `LIBC_NAMESPACE_DECL` version because that implies visibility.

 [libc][stdio] Use proxy headers of stdio.h in src and test folders. (#110067) 2024-10-01T15:48:07+00:00 lntue lntue@google.com 2024-10-01T15:48:07+00:00 c63112a9118277a20ae440f3f69189c0937e8f4d https://github.com/llvm/llvm-project/issues/60481

 [libc] Implement (v|f)printf on the GPU (#96369) 2024-07-13T00:36:13+00:00 Joseph Huber huberjn@outlook.com 2024-07-13T00:36:13+00:00 40effc7af5679b7d54d3176a5eef2cdee1962ecd Summary: This patch implements the `printf` family of functions on the GPU using the new variadic support. This patch adapts the old handling in the `rpc_fprintf` placeholder, but adds an extra RPC call to get the size of the buffer to copy. This prevents the GPU from needing to parse the string. While it's theoretically possible for the pass to know the size of the struct, it's prohibitively difficult to do while maintaining ABI compatibility with NVIDIA's varargs. Depends on https://github.com/llvm/llvm-project/pull/96015.
