linux-user: Implement VDSOs
|
expand
|
Still no integrated cross-compile, however: Changes for v4: * Force all vdso to have a single load segment. This will prevent problems with varying host/guest page size. * Tidy some of the assembly with macros. * Implement loongarch, ppc, s390x. Just in case the list eats a binary: https://gitlab.com/rth7680/qemu/-/tree/lu-vdso r~ Richard Henderson (18): linux-user: Introduce imgsrc_read, imgsrc_read_alloc linux-user: Tidy loader_exec linux-user: Do not clobber bprm_buf swapping ehdr linux-user: Use ImageSource in load_elf_image linux-user: Use ImageSource in load_symbols linux-user: Replace bprm->fd with bprm->src.fd linux-user:
