Raw Normal View History

Lots of build system cleanup and documentation This splits mk/stageN.mk into host.mk and target.mk and makes the build rules somewhat simpler - there's no more building from stageN into stageN+1; instead we always build from stageN(host) to stageN(target) then promote from stageN(target) to stageN+1(host). Add a big honkin explaination right at the top of Makefile.in

Abstract the build directories further in the makefiles This defines variables for host bin and lib directories as well as all target bin and lib directories then uses them everywhere.

$(HOST_LIB0)/$(CFG_STDLIB): $(HOST_BIN0)/rustc$(X)
Build stage0/lib/libstd.so using the stage0 compiler. This essentially starts the bootstrapping one step earlier by building the stdlib from source using the stage0 compiler and then using that stdlib to build the stage1 compiler. (Instead of starting by building the stage1 compiler and then building a stdlib with it). This means we should now be able to add features to the stdlib and use them in the compiler without having to do a snapshot. (On the flip side, this means that we now need to do a snapshot if we want to use a new language feature in the stdlib, but that doesn't really seem too burdensome (we already need to snapshot if we want to use a new language feature in the compiler)).

Move llvm out of stageN/lib so that the host building stage 1+ can have a newer and incompatible llvm with the bots.
