Define rustc's host triple at compile time This way a cross-compiled rustc's answer to host_triple() is correct. The return value of host_triple() reflects the actual host triple that the compiler was build for, not the triple the compiler is being built on
2013-05-25 01:05:31 -05:00
# This is the compile-time target-triple for the compiler. For the compiler at
# runtime, this should be considered the host-triple. More explanation for why
# this exists can be found on issue #2400

# The standard libraries should be held up to a higher standard than any old
# code, make sure that these common warnings are denied by default. These can
# be overridden during development temporarily. For stage0, we allow all these
# to suppress warnings which may be bugs in stage0 (should be fixed in stage1+)
# NOTE: add "-A warnings" after snapshot to WFLAGS_ST0

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).

Define _RUST_STAGEN when building rustrt. This lets us use #ifdefs to determine which stage of the build we happen to be in, which is useful in the event we need to make changes to rustrt that are incompatible with the code generated by stage0.
