The purpose of these headers is to fix issues with mingw v4.0, as described in #9246. This works by adding this directory to GCC include search path before mingw system headers directories, so we can intercept their inclusions and add missing definitions without having to modify files in mingw/include. 2013-09-17 03:06:01 -05:00			`$$(Q)$$(MAKE) -C $$(CFG_LLVM_BUILD_DIR_$(1)) $$(CFG_LLVM_BUILD_ENV_$(1))`

Remove unused upcalls The main one removed is rust_upcall_reset_stack_limit (continuation of #10156), and this also removes the upcall_trace function. The was hidden behind a `-Z trace` flag, but if you attempt to use this now you'll get a linker error because there is no implementation of the 'upcall_trace' function. Due to this no longer working, I decided to remove it entirely from the compiler (I'm also a little unsure on what it did in the first place). 2013-11-28 16:16:17 -06:00			`@$$(call E, make: cleaning llvm)`
