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 08:05:31 +02:00
# 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

# Every recipe in TARGET_STAGE_N outputs to $$(TLIB$(1)_T_$(2)_H_$(3),
# a directory that can be cleaned out during the middle of a run of
# the get-snapshot.py script. Therefore, every recipe needs to have
# an order-only dependency either on $(SNAPSHOT_RUSTC_POST_CLEANUP) or
# on $$(TSREQ$(1)_T_$(2)_H_$(3)), to ensure that no products will be
# put into the target area until after the get-snapshot.py script has
# had its chance to clean it out; otherwise the other products will be
# inadvertantly included in the clean out.

Fix #3225: Incorporate feedback from Graydon. Namely, switched in many places to using GNU make provided functions for directory listing and text processing, rather than spawning a shell process to do that work. In the process of the revision, learned about Target-specific variables, which were very applicable to INSTALL_LIB (which, on a per-recipe basis, was always receiving the same actual arguments for its first two formal parameters in every invocation). http://www.gnu.org/software/make/manual/html_node/Target_002dspecific.html (We might be able to make use of those in future refactorings.) ---- Also adds a cleanup pass to get-snapshot.py as well, since the same problem arises when we unpack libraries from the snapshot archive into a build directory with a prior snapshot's artifacts. (I put this step into the python script rather than the makefile because I wanted to delay the cleanup pass until after we have at least successfully downloaded the tarball. That way, if the download fails, you should not destroy the previous unarchived snapshot libraries and build products.) ---- Also reverted whitespace changes to minimize diff.

Add dependence arc from running rustc to its libraries. This commit fixes some oversights in the Makefile where rustc could be invoked without some of its dependencies yet in place. (I encountered the problem in practice; its not just theoretical.) As written in Makefile.in, $(STAGE$(1)_T_$(2)_H_$(3)) is the way one writes an invocation of rustc where $(1) is the stage number $(2) is the target triple $(3) is the host triple. (Other uses of the macro may plug in actual values or different parameters in for those three formal parameters.) When you have invocations of $(STAGE...), you need to make sure that its dependences are satisfied; otherwise, if someone is using `make -jN` for certain (large-ish) `N`, one can encounter situations where GNU make attempts to invoke `rustc` before it has actually copied some of its libraries into place, such as libmorestack.a, which causes a link failure when the rustc invocation attempts to link in those libraries. In this case, the main prerequisite to add is TSREQ$(1)_T_$(2)_H_$(3), which is described in Makefile.in as "Prerequisites for using the stageN compiler to build target artifacts" ---- In addition to adding the extra dependences on TSREQ..., I also replaced occurrences of the pattern: TSREQ$(1)_T_$(2)_H_$(3) $$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_STDLIB_$(2)) $$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_EXTRALIB_$(2)) with: SREQ$(1)_T_$(2)_H_$(3) which is equivalent to the above, as defined in Makefile.in ---- Finally, for the cases where TSREQ was missing in tests.mk, I went ahead and put in a dependence on SREQ rather than just TSREQ, since it was not clear to me how one could expect to compile those cases without stdlib and extralib. (It could well be that I should have gone ahead and done the same in other cases where I saw TSREQ was missing, and put SREQ in those cases as well. But this seemed like a good measure for now, without needing to tax my understanding of the overall makefile infrastructure much further.)

Fix #3225: Incorporate feedback from Graydon. Namely, switched in many places to using GNU make provided functions for directory listing and text processing, rather than spawning a shell process to do that work. In the process of the revision, learned about Target-specific variables, which were very applicable to INSTALL_LIB (which, on a per-recipe basis, was always receiving the same actual arguments for its first two formal parameters in every invocation). http://www.gnu.org/software/make/manual/html_node/Target_002dspecific.html (We might be able to make use of those in future refactorings.) ---- Also adds a cleanup pass to get-snapshot.py as well, since the same problem arises when we unpack libraries from the snapshot archive into a build directory with a prior snapshot's artifacts. (I put this step into the python script rather than the makefile because I wanted to delay the cleanup pass until after we have at least successfully downloaded the tarball. That way, if the download fails, you should not destroy the previous unarchived snapshot libraries and build products.) ---- Also reverted whitespace changes to minimize diff. I plan to put them back in in a dedicated commit elsewhere.

Make build products depend on their target directories. This is an attempt to address Issue #3326 by adding [*order-only*][1] prerequsites of each build product on the directory where it is to go. It is important that the prerequisites be order-only, since the timestamp on a parent directory is not relevant to whether a product is out of date; the parent directory merely needs to exist. (This use case of generating target directories was provided as an [example][2] of how order-only prequisites are used.)

Add dependence arc from running rustc to its libraries. This commit fixes some oversights in the Makefile where rustc could be invoked without some of its dependencies yet in place. (I encountered the problem in practice; its not just theoretical.) As written in Makefile.in, $(STAGE$(1)_T_$(2)_H_$(3)) is the way one writes an invocation of rustc where $(1) is the stage number $(2) is the target triple $(3) is the host triple. (Other uses of the macro may plug in actual values or different parameters in for those three formal parameters.) When you have invocations of $(STAGE...), you need to make sure that its dependences are satisfied; otherwise, if someone is using `make -jN` for certain (large-ish) `N`, one can encounter situations where GNU make attempts to invoke `rustc` before it has actually copied some of its libraries into place, such as libmorestack.a, which causes a link failure when the rustc invocation attempts to link in those libraries. In this case, the main prerequisite to add is TSREQ$(1)_T_$(2)_H_$(3), which is described in Makefile.in as "Prerequisites for using the stageN compiler to build target artifacts" ---- In addition to adding the extra dependences on TSREQ..., I also replaced occurrences of the pattern: TSREQ$(1)_T_$(2)_H_$(3) $$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_STDLIB_$(2)) $$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_EXTRALIB_$(2)) with: SREQ$(1)_T_$(2)_H_$(3) which is equivalent to the above, as defined in Makefile.in ---- Finally, for the cases where TSREQ was missing in tests.mk, I went ahead and put in a dependence on SREQ rather than just TSREQ, since it was not clear to me how one could expect to compile those cases without stdlib and extralib. (It could well be that I should have gone ahead and done the same in other cases where I saw TSREQ was missing, and put SREQ in those cases as well. But this seemed like a good measure for now, without needing to tax my understanding of the overall makefile infrastructure much further.)
