+Subject: [PATCH] [compiler-rt] Hardcode uptr/sptr typedefs on Mips/Linux
+
+Sanitizer build on Mips/Linux faills to build due to assertion errors
+mismatched definitions. This is due to inconsistent definitions of
+`uptr` of either `unsigned long` or `unsigned int` in compiler-rt. This
+is caused by clang defining
+
+__UINTPTR_TYPE__ long unsigned int where as gcc defines it as
+unsigned int
+
+As a workaround, this hardcodes `uptr`/`sptr` in compiler-rt to
+`unsigned int`/`int` on Linux Mips, matching gcc.
+
+Upstream-Status: Submitted [https://github.com/llvm/llvm-project/pull/141201]
