most of the run-make tests could be silently passing on cases that should fail #13746

Makefiles unfortunately do not error on undefined variable references; they just silently expand into an empty string. And an empty string is also not an invalid command in a recipe.

So, a recipe like this (observe highlighted line): run-make/dylib-chain/Makefile

does not actually work because of this: run-make/tools.mk

because $(call FAIL,main) is going to expand into an empty string; what was wanted was $(call FAILS,main)

Although it looks like most of the tests are using $(call FAIL,xxx), so its probably simpler to just change tools.mk to use the name FAIL instead of FAILS:

% ack FAIL
bootstrap-from-c-with-green/Makefile
11: $(call FAIL,main)

bootstrap-from-c-with-native/Makefile
10: $(call FAIL,main)

c-dynamic-dylib/Makefile
13: $(call FAIL,bar)

c-dynamic-rlib/Makefile
13: $(call FAIL,bar)

c-link-to-rust-dylib/Makefile
9:  $(call FAIL,bar)

c-static-dylib/Makefile
10: $(call FAIL,bar)

dylib-chain/Makefile
12: $(call FAIL,m4)

prefer-dylib/Makefile
8:  $(call FAILS,foo)

tools.mk
13:FAILS = $(TARGET_RPATH_ENV) ( $(RUN_BINFILE) && exit 1 || exit 0 )

(The bigger question is whether attempting to implement this fix is going to actually expose latent bugs...)

run-make tests must distinguish between HOST_RPATH and TARGET_RPATH.
d89b98a 
What this commit does:

* Pass both of the (newly introduced) HOST and TARGET rpath setup vars
  to `maketest.py`

* Update `maketest.py` to no longer update the LD_LIBRARY_PATH itself
  Instead, it passes along the HOST and TARGET rpath setup vars in
  environment variables `HOST_RPATH_ENV` and `TARGET_RPATH_ENV`

* Cleanup: Distinguish in tools.mk between the command to run (`RUN`)
  and the file to generate to drive that command (`RUN_BINFILE`).  The
  main thing this enables is that `RUN` can now setup the
  `TARGET_RPATH_ENV` without having to dirty up the runner code in
  each of the `run-make` Makefiles.

I should have tried to fix rust-lang#13746 but I got distracted, and decided
fixing that is orthgonal to the changes in this branch of work.

Note that even with these changes, `make check-stage1` still does not
work all the way to completion.  (It just gets further than it did
before, but still breaks down in the `run-make` tests.)

Fix syntactic mistake in earlier definition of FAILS.

(Note that most tests are not using FAILS anyway, due to rust-lang#13746.)

Fix #13732.

This is a revised, much less hacky form of PR #13753

The changes here:

 * add instrumentation to aid debugging of linkage errors,
 * fine tune some things in the Makefile where we are telling binaries to use a host-oriented path for finding dynamic libraries, when it should be feeding the binaries a target-oriented path for dynamic libraries.
 * pass along the current stage number to run-make tests, and
 * skip certain tests when running atop stage1.

Fix #13746 as well.

Auto merge of rust-lang#13746 - feniljain:fix_extract_function, r=jon…

fix: make make_body respect comments in extract_function

Possible fix for rust-lang#13621

### Points to help in review:

- Earlier we were only considering statements in a block expr and hence comments were being ignored, now we handle tokens hence making it aware of comments and then preserving them using `hacky_block_expr_with_comments`

Seems like I am not able to attach output video, github is glitching for it :(
