Subject: [RFC v3 0/1] xtensa FDPIC port
Hello,
this is the third RFC version of the xtensa FDPIC port for musl.
It corresponds to the xtensa FDPIC ABI specification version 1
available here:
https://github.com/jcmvbkbc/xtensa-abi/blob/master/fdpic-xtensa.txt
The following binutils and gcc can be used to build the
xtensa-linux-muslfdpic toolchain:
https://github.com/jcmvbkbc/binutils-gdb-xtensa tag xtensa-fdpic-abi-spec-1.2
https://github.com/jcmvbkbc/gcc-xtensa tag xtensa-fdpic-abi-spec-1.2
I've tested this version with libc-test using QEMU linux-user and full
system emulation. The results in the linux-user are the following:
FAIL src/functional/pthread_mutex_pi-static.exe [status 1]
FAIL src/functional/pthread_mutex_pi.exe [status 1]
FAIL src/functional/pthread_robust-static.exe [timed out]
FAIL src/functional/pthread_robust.exe [timed out]
FAIL src/functional/strptime-static.exe [status 1]
FAIL src/functional/strptime.exe [status 1]
FAIL src/math/acoshl.exe [status 1]
FAIL src/math/asinhl.exe [status 1]
FAIL src/math/erfcl.exe [status 1]
FAIL src/math/fma.exe [status 1]
FAIL src/math/fmal.exe [status 1]
FAIL src/math/lgammal.exe [status 1]
FAIL src/math/tgammal.exe [status 1]
FAIL src/regression/pthread-robust-detach-static.exe [status 1]
FAIL src/regression/pthread-robust-detach.exe [status 1]
functional/ and regression/ pthread-related failures are expected
because PI mutexes and robust list functions are not available in
the linux-user mode. These particular tests pass in full system
emulation.
math tests fail with ULP differences.
