2022-04-06Replace TARGET_WORDS_BIGENDIANMarc-André Lureau
Convert the TARGET_WORDS_BIGENDIAN macro, similarly to what was done with HOST_BIG_ENDIAN. The new TARGET_BIG_ENDIAN macro is either 0 or 1, and thus should always be defined to prevent misuse.

2019-05-13Clean up ill-advised or unusual header guardsMarkus Armbruster
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.

2018-04-01target/xtensa: linux-user: fix sysv IPC structuresMax Filippov
- make target_ipc_perm fields match kernel definitions for xtensa; - add target_semid64_ds with proper order of times and reserved fields for little/big endian specific for xtensa; - add missing reserved fields after time fields to the target_shmid_ds; - fix types of shm_cpid, shm_lpid and shm_nattch fields of target_shmid_ds to match kernel definitions for xtensa. These changes fix guest ipcs output and fix glibc testsuite tests sysvipc/test-sysvsem and sysvipc/test-sysvshm.

2018-03-16target/xtensa: add linux-user supportMax Filippov
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).
