* linux-user: xtensa: Remove unused constant TARGET_NR_syscall_countAleksandar Markovic2020-02-171-2/+0Star
| | | | | | | | | | | | | Currently, there is no usage of TARGET_NR_syscall_count for target xtensa, and there is no obvious indication if there is some planned usage in future.

* Clean up ill-advised or unusual header guardsMarkus Armbruster2019-05-131-3/+3
| | | | | | | | | | | | | | Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions. Done with scripts/clean-header-guards.pl.

* target/xtensa: add linux-user supportMax Filippov2018-03-161-0/+437
Import list of syscalls from the kernel source. Conditionalize code/data that is only used with softmmu. Implement exception handlers. Implement signal hander (only the core registers for now, no coprocessors or TIE).
