The build variants enable group of checks offered by clang
UndefinedBehaviorSanitizer detector.
Add sanitizers suppression file in .ci/blacklist.supp based on
copy of the file from Boost.Beast.
Update Travis CI:
- Add .ci/build-and-test.sh script as handy proxy for b2 command.
- Add build jobs for each of the three new UBSan variants.
- Display COMPILER and VARIANT first as these two are most important
details while inspecting the build matrix
(TOOLSET can be derived from COMPILER).

# LLVM/clang sanitizers suppression file for Boost.GIL
|
|
#
|
|
# Copied from https://github.com/boostorg/beast/blob/develop/tools/blacklist.supp
|
|
#
|
|
# Remember that this blacklist file is GLOBAL to all sanitizers
|
|
# Be therefore extremely careful when considering to add a sanitizer
|
|
# filter here instead of using a runtime suppression
|
|
#
|
|
# Remember also that filters here quite literally completely
|
|
# remove instrumentation altogether, so filtering here means
|
|
# that sanitizers such as tsan will false positive on problems
|
|
# introduced by code filtered here.
|
|
#
|
|
# The main use for this file is ubsan, as it's the only sanitizer
|
|
# without a runtime suppression facility.
|
|
#
|
|
# Be ESPECIALLY careful when filtering out entire source files!
|
|
# Try if at all possible to filter only functions using fun:regex
|
|
# Remember you must use mangled symbol names with fun:regex
