c9663b1685 Fix sometimes-spurious warning about changed config.h
After backing up and restoring config.h, `git diff-files` may report
it as potentially-changed because it isn't sure whether the index is
up to date. To avoid this, make sure that the git index is up-to-date.

This fixes the warning about changed config.h that you might get when
you run all.sh twice in succession, yet if you run `git status` or
`git diff` everything seems up to date and you no longer get the
warning because these git commands update the index.

53084872ab all.sh: only look for armcc if it is used
Only look for armcc if component_build_armcc or component_build_yotta
is to be executed, instead of requiring the option --no-armcc.

You can still pass --no-armcc, but it's no longer required when
listing components to run. With no list of components or an exclude
list on the command line, --no-armcc is equivalent to having
build_armcc in the exclude list.

Omit the yotta pre-checks if the build_yotta component is not going to
be executed. This makes --no-yotta equivalent to specifying a list of
components to run that doesn't include build_yotta.

3fbdd21ca5 Add conditional component inclusion facility
Add a conditional execution facility: if a function support_xxx exists

command line lists an explicit set of components to execute).

Use this facility for the 64-bit-specific or amd64-specific components.

770ad7e2c9 all.sh: don't insist on Linux; always run Valgrind
Don't bail out of all.sh if the OS isn't Linux. We only expect
everything to pass on a recent Linux x86_64, but it's useful to call
all.sh to run some components on any platform.

In all.sh, always run both MemorySanitizer and Valgrind. Valgrind is
slower than ASan and MSan but finds some things that they don't.

Run MSan unconditionally, not just on Linux/x86_64. MSan is supported
on some other OSes and CPUs these days.

Use `all.sh --except test_memsan` if you want to omit MSan because it
isn't supported on your platform. Use `all.sh --except test_memcheck`
if you want to omit Valgrind because it's too slow.

Portability: ecognize amd64 (FreeBSD arch string) as well as x86_64
(Linux arch string) for `uname -m`. The `make` utility must still
be GNU make.

4e7b323fd8 Use CMAKE_BUILD_TYPE to do Asan builds
Use `cmake -D CMAKE_BUILD_TYPE=Asan` rather than manually setting
`-fsanitize=address`. This lets cmake determine the necessary compiler
and linker flags.

With UNSAFE_BUILD on, force -Wno-error. This is necessary to build
with MBEDTLS_TEST_NULL_ENTROPY.

72adb432bc Back up and restore config.h systematically
In all.sh, always save config.h before running a component, instead of
doing it manually in each component that requires it (except when we
forget, which has happened). This would break a script that requires
config.h.bak not to exist, but we don't have any of those.

1a2ca72ddc Break up the tests into components
Split the long list of tests into individual functions. Each time the
test code called the `cleanup` function, I start a new function called
`component_xxx`.

Run all the components by enumerating the `component_xxx` functions.
After running each component, call `cleanup`.

A few sanity checks didn't have calls to `cleanup` because they didn't
need them. I put them into separate components anyway, so there are
now a few extra harmless calls to `cleanup`.

57db6ff938 Move the code into functions. No behavior change.
Move almost all the code of this script into functions. There is no
intended behavior change. The goal of this commit is to make
subsequent improvements easier to follow.

A very large number of lines have been reintended. To see what's going
on, ignore whitespace differences (e.g. diff -w).

I followed the following rules:

* Minimize the amount of code that gets moved.
* Don't change anything to what gets executed or displayed.
* Almost all the code must end up in a function.

This commit is in preparation for breaking up the sequence of tests
into individual components that can run independently.

bda9abf696 Add a facility to skip running some test suites
With the build option SKIP_TEST_SUITES=..., the specified test suites
are built, but skipped when running tests. Usage:
    make check SKIP_TEST_SUITES=timing,gcm
or
    cmake -D SKIP_TEST_SUITES=timing,gcm ...

The list can be separated by any of space, comma or semicolon, and each
element can be a regular expression in ERE syntax except that "." stands
for itself. Skipping "foo" skips not only "foo" itself but also
any "foo.bar", but does not skip "foobar".

3400b4dbd6 check-files: exclude .git and third-party files
Exclude ".git" directories anywhere. This avoids spurious errors in git
checkouts that contain branch names that look like a file
check-files.py would check. Fix #1713

Exclude "mbed-os" anywhere and "examples" from the root. Switch to the
new mechanism to exclude "yotta/module". These are directories where
we store third-party files that do not need to match our preferences.

Exclude "cov-int" from the root. Fix #1691

d620f6f56b Adds a filter to run-test-suites.pl to exclude data files
The run-test-suites.pl script was executing all files of the form 'test_suite*'
which were either executable or ended with a .exe extension.

On some filesystems, such as through network shares or VMs, which are
abstracting one set of file permissions to Unix permissions, may set the
executable permissions on all files, whether they're executable or not.

That was leading to the run-test-suites.pl script to attempt to execute the .c
intermediate files because they followed the form 'test_suite_*.c'. This change
now excludes them, just in case they accidentally have execute permissions.

Also, in that case the flags were either redundant (-Werror etc) or wrong

be disabled).

variety. This caught an uninitialized variable warning in cmac.c that
builds without -O didn't catch.

0afe624fff all.sh: add test with MBEDTLS_DEPRECATED_REMOVED 2018-02-21 19:28:12 +01:00

14c3c0610e Test with 32-bit and 64-bit bignum limbs on all architectures
Build with MBEDTLS_HAVE_INT32 and MBEDTLS_HAVE_INT64 on all
architectures, not just x86_64. These two modes should work on all
platforms (except embedded environments where 64-bit division is not
available).

Also run the unit tests.

Correct the description: this is not "N-bit compilation", but "N-bit
bignum limbs".

48e689e6be Remove duplicate build run
Don't compile twice with MBEDTLS_HAVE_INT64.

But do test with MBEDTLS_HAVE_INT32.

e963efa110 Don't limit RSA_NO_CRT test in all.sh to 64-bit systems
Compilation and test for the `MBEDTLS_RSA_NO_CRT` option were
previously guarded by a check for 64-bit systems, for which there
is no reason. This commit moves both outside of the guard.

bca6ab9d38 all.sh: new option --no-armcc
With this option, don't run anything that requires armcc or yotta, so
the script can run offline.

decide to make no-yotta the default in the future.

7c6521688a all.sh: --keep-going mode
Add --keep-going mode to all.sh. In this mode, if a test fails, keep
running the subsequent tests. If a build fails, skip any tests of this
build and move on to the next tests. Errors in infrastructure, such as
git or cmake runs, remain fatal. Print an error summary at the end of
the run, and return a nonzero code if there was any failure.

In known terminal types, use color to highlight errors.

On a fatal signal, interrupt the run and report the errors so far.
