# OS#4062: Some gcc version (< 7.3.0) on ARM generate wrong code for __thread
# variables that crash at runtime. It seems, due to some unknown reason, that we
# are not affected by this bug with toolchain from poky pyro (6.4.0). However,
# libosmocore as of e188b8cd98f599468fbb200c7d590de955daf761 applies some
# CFLAGS="-mtls-dialect=gnu2" to workaround the issue automatically. But same
# toolchain contains an "ld" that crashes when those flags are applied.
# Fortunately, libosmocore provides a way to disable the workaround, and since
# we are not affected by the bug, we are fine with that. If the toolchain had
# the TLS runtime bug, then we'd had to build with -O0. Can be probably dropped
# once we move to newer toolchain.
#EXTRA_OECONF +=  "--disable-detect-tls-gcc-arm-bug"
# UPDATE: OS#5079: we stop using "--disable-detect-tls-gcc-arm-bug" because we
# finally hit the TLS bug in sysmobts (osmo-bts-symo calling osmo_str_tolower()
# which uses "static __thread char capsbuf"). As a result, the only option would
# be to use -O0 when building libosmocore with the sysmobts toolchain. In order
# to avoid that, we take advantage of the fact that no libosmocore multi-thread
# process is expected to run there and simply drop all the "__thread"
# references when building for sysmobts. That's done as a machine-specific
# bbappend in meta-sysmocom-bsp.
