- Subject: [Patch,testsuite,AVR]: target-supports.exp: AVR does not support TLS
The auto-detect machinery fails to correctly detect that TLS is not supported
on AVR. This leads to gross noise of several hundreds of FAILs in testsuite.
This patch explicitly tells that AVR doesn't support TLS.
Lightly tested with testsuite run on avr-unknown-none where tests like
gcc.dg/debug/tls-1.c ran into ICE are UNSUPPORTED now.
Okay for trunk?
testsuite/
* lib/target-supports.exp (check_effective_target_tls): AVR has no
support for TLS.
(check_effective_target_tls_native): Ditto.
(check_effective_target_tls_emulated): Ditto.
(check_effective_target_tls_runtime): Ditto.
