Usage: $0 [FLAGS]...
Validate GHC source tree against testsuite; see
https://gitlab.haskell.org/ghc/ghc/wikis/testing-patches for more
information.
Flags:
--no-clean don't clean first, just carry on from
a previous interrupted validation run
--testsuite-only don't build the compiler, just run the test suite
--build-only don't test the compiler, just build it
--hpc build stage2 with -fhpc, and see how much of the
compiler the test suite covers.
2008-07-01: 63% slower than the default.
HTML generated here: testsuite/hpc_output/hpc_index.html
--fast Omit binary distribution. Omit certain tests.
--slow Build stage2 with -DDEBUG. Run tests for all WAYS,
but skip those that call compiler_stats_num_field.
2008-07-01: 14% slower than the default.
--quiet More pretty build log.
See Note [Default build system verbosity].
--stack Use Stack to build Hadrian and to provide the bootstrap
compiler.
--ignore-perf-all Use Hadrian's user settings to ask the "runtests" driver
to ignore all changes in performance tests
--ignore-perf-incrs Use Hadrian's user settings to ask the "runtests" driver
to ignore increases in performance tests
--ignore-perf-decrs Use Hadrian's user settings to ask the "runtests" driver
to ignore decreases in performance tests
--debug Use inbuilt Hadrian flag to generate information for debugging
--help shows this usage help.
validate runs 'hadrian/build -j\$THREADS', where by default THREADS is the
number of cpus your computer has +1. You can set the environment variable
THREADS to override this. For a sequential build you would for example use
THREADS=1 ./validate
You can set the 'config_args' environment variable to pass flags to
'configure'.
You can also use environment variables to pass extra options to the
testsuite. For example:
TEST='read001 read002' ./validate --testsuite-only --fast
Note on BINDIST variable: The BINDIST variable value indicates whether a binary
distribution of GHC built using Hadrian/Make is to be installed. When set
to "YES", it indicates that a path, previously set with the --prefix flag in
the configuration step (./configure), can be used as the installation location.
Otherwise the binary executables built are placed in sub-directories within
the "./_validatebuild" directory.
Note on validate vs GitLab CI setup: This script is distinct from the
collection of validation settings used by the GitLab Continuous Integration
system (details in ./.gitlab-ci.yml) and can be run locally on a user's computer
system. The CI scripts are stored in the ./.gitlab directory for reference.
