Commit Message

Alex Bennée May 25, 2018, 2:19 p.m. UTC
This make is now invoked from each individual target make with the
appropriate CC and EXTRA_CFLAGS set for each guest. It then includes
additional Makefile.targets from:

  - tests/tcg/multiarch (always)
  - tests/tcg/$(TARGET_BASE_ARCH) (if available)
  - tests/tcg/$(TARGET_NAME)

The order is important as the later Makefile's may want to suppress
TESTS from its base arch profile. Each included Makefile.target is
responsible for adding TESTS as well as defining any special build
instructions for individual tests.

Should we use --preserve-status here?

I'm getting Error 124:

       If the command times out, and  --preserve-status  is  not  set,
       then  exit with status 124.  Otherwise, exit with the status of
       COMMAND.  If no signal is specified, send the TERM signal  upon
       timeout.  The TERM signal kills any process that does not block
       or catch that signal.  It may be necessary to use the KILL  (9)
       signal,  since  this signal cannot be caught, in which case the
       exit status is 128+9 rather than 124.

I guess it only really matters if the test cases are going to catch and
handle TERM signals. Currently I think any non-zero response is enough
to exit make.

+# These are complicated by the fact we want to build them for guest
+# systems. This requires knowing what guests we are building and which
+# ones we have cross-compilers for or docker images with
+# cross-compilers.
+#
+# The tests themselves should be as minimal as possible as
+# cross-compilers don't always have a large amount of libraries
+# available.
+#
+# We only include the host build system for SRC_PATH and we don't
+# bother with the common rules.mk. We expect the following:
+#
+#   CC - the C compiler command
+#   EXTRA_CFLAGS - any extra CFLAGS
+#   BUILD_STATIC - are we building static binaries
+#
+# By default all tests are statically compiled but some host systems
+# may not package static libraries by default. If an external
+# cross-compiler can only build dynamic libraries the user might need
+# to make extra efforts to ensure ld.so can link at runtime when the
+# tests are run.
+#
+# We also accept SPEED=slow to enable slower running tests
+#
+# We also expect to be in the tests build dir for the FOO-linux-user.
