2018-06-20tests: add top-level make dependency for docker buildsAlex Bennée1-0/+31
One problem with satisfying your docker dependencies in a sub-make it you might end up trying to satisfy the dependency multiple times. This is especially a problem with debian-sid based cross compilers and CI setups. We solve this by doing a docker build pass at the top level before any sub-makes are called. We still need to satisfy dependencies in the Makefile.target call so people can run tests from individual target directories. We introduce a new Makefile.probe which gets called for each PROBE_TARGET and allows us to build up the list. It does require multiply including config-target.mak which shouldn't cause any issues as it shouldn't define anything that clashes with config-host.mak. However we undefine a few key variables each time around. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

Now all the build infrastructure is in place we can build tests for each guest that we support. That support mainly depends on having cross compilers installed or docker setup.

2018-06-20tests/tcg/Makefile: update to be called from Makefile.targetAlex Bennée1-107/+76
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.

2018-03-26target/xtensa: fix timers testMax Filippov1-1/+1
The value of CCOUNT special register is calculated as time elapsed since CCOUNT == 0 multiplied by the core frequency. In icount mode time increment between consecutive instructions that don't involve time warps is constant, but unless the result of multiplication of this constant by the core frequency is a whole number the CCOUNT increment between these instructions may not be constant. E.g. with icount=7 each instruction takes 128ns, with core clock of 10MHz CCOUNT values for consecutive instructions are: 502: (128 * 502 * 10000000) / 1000000000 = 642.56 503: (128 * 503 * 10000000) / 1000000000 = 643.84 504: (128 * 504 * 10000000) / 1000000000 = 645.12 I.e.the CCOUNT increments depend on the absolute time. This results in varying CCOUNT differences for consecutive instructions in tests that involve time warps and don't set CCOUNT explicitly. Change frequency of the core used in tests so that clock cycle takes exactly 64ns. Change icount power used in tests to 6, so that each instruction takes exactly 1 clock cycle. With these changes CCOUNT increments only depend on the number of executed instructions and that's what timer tests expect, so they work correctly.

2018-01-16maint: Fix macros with broken 'do/while(0); ' usageEric Blake1-1/+1
The point of writing a macro embedded in a 'do { ... } while (0)' loop (particularly if the macro has multiple statements or would otherwise end with an 'if' statement) is so that the macro can be used as a drop-in statement with the caller supplying the trailing ';'. Although our coding style frowns on brace-less 'if': if (cond) statement; else something else; that is the classic case where failure to use do/while(0) wrapping would cause the 'else' to pair with any embedded 'if' in the macro rather than the intended outer 'if'. But conversely, if the macro includes an embedded ';', then the same brace-less coding style would now have two statements, making the 'else' a syntax error rather than pairing with the outer 'if'. Thus, even though our coding style with required braces is not impacted, ending a macro with ';' makes our code harder to port to projects that use brace-less styles. The change should have no semantic impact. I was not able to fully compile-test all of the changes (as some of them are examples of the ugly bit-rotting debug print statements that are completely elided by default, and I didn't want to recompile with the necessary -D witnesses - cleaning those up is left as a bite-sized task for another day); I did, however, audit that for all files touched, all callers of the changed macros DID supply a trailing ';' at the callsite, and did not appear to be used as part of a brace-less conditional.

2017-07-11tests: Avoid non-portable 'echo -ARG'Eric Blake1-4/+4
POSIX says that backslashes in the arguments to 'echo', as well as any use of 'echo -n' and 'echo -e', are non-portable; it recommends people should favor 'printf' instead. This is definitely true where we do not control which shell is running (such as in makefile snippets or in documentation examples). But even for scripts where we require bash (and therefore, where echo does what we want by default), it is still possible to use 'shopt -s xpg_echo' to change bash's behavior of echo. And setting a good example never hurts when we are not sure if a snippet will be copied from a bash-only script to a general shell script (although I don't change the use of non-portable \e for ESC when we know the running shell is bash). Replace 'echo -n "..."' with 'printf %s "..."', and 'echo -e "..."' with 'printf %b "...\n"', with the optimization that the %s/%b argument can be omitted if the string being printed is a strict literal with no '%', '$', or '`' (we could technically also make this optimization when there are $ or `` substitutions but where we can prove their results will not be problematic, but proving that such substitutions are safe makes the patch less trivial compared to just being consistent). In the qemu-iotests check script, fix unusual shell quoting that would result in word-splitting if 'date' outputs a space. In test 051, take an opportunity to shorten the line. In test 068, get rid of a pointless second invocation of bash.
