Fix the Android build again

2026-05-28T03:31:16Z

* exec/trace.c (ARRAYELTS, establish_seccomp_filter): Restore ARRAYELTS, since Gnulib is not available in the exec library.

ARRAYELTS → countof

2026-05-27T04:57:20Z

C2y will standardize countof as the macro that Emacs uses the name ARRAYELTS for. Switch to the standard name, which is supported by GCC 16+, by Clang 21, and by the Gnulib stdcountof-h module already in use for compilers that do not support countof. Also, use countof in a few places where we missed using ARRAYELTS. * admin/coccinelle/arrayelts.cocci: Suggest countof, not ARRAYELTS. * admin/merge-gnulib (GNULIB_MODULES): Add stdcountof-h, as it is now a direct rather than an indirect dependency. * exec/trace.c, src/lisp.h, src/sfnt.c: Include . (ARRAYELTS): Remove. All uses replaced by countof. * lib-src/ebrowse.c, lib-src/etags.c, lib-src/make-docfile.c: * lib-src/seccomp-filter.c, lwlib/lwlib-Xaw.c: Prefer and countof to doing things by hand.

Revert "Don’t silently truncate file names in exec.c"

2026-05-25T03:21:00Z

This reverts commit 3461b450c5eae3ed53192aa9514e0b1ac1b1c8f2. Gnulib and intprops.h are not available from within the exec helper.

Don’t silently truncate file names in exec.c

2026-05-24T02:18:53Z

* exec/exec.c (format_pid): Simplify. No need for a local array. (exec_0): Shrink local buffer. If names are too long, fail instead of silently truncating them. Be cautious in case symlink is zero length (shouldn’t be possible in Android, but it’s easy to be safe).

Port recent Android changes to mips64el

2025-04-15T08:17:14Z

* exec/config-mips.m4.in (DADDI2, DADDI3): Disable at-clobbering by assembler macros expressly. * exec/loader-mips64el.s: Adapt from loader-mipsel.s. * exec/configure.ac (exec_cv_as_daddi): Properly escape reg names. * exec/exec.c (struct exec_jump_command, exec_0): Don't define or set `fpu_mode' if __LP64__. * exec/exec.h (struct exec_tracee): New field `callno'. * exec/trace.c (process_system_call): Always record the current system call number in TRACEE lest it should be required once it has been overwritten upon the syscall's completion. (seccomp_system_call): Likewise. (after_fork): Clear `tracee->callno'.

Replace AT_EXECFN in auxiliary vectors of programs executed on Android

2025-04-13T10:51:49Z

* exec/exec.c (insert_args, exec_0): On non-MIPS systems, copy NAME and its length to the loader area. State that MIPS support is not yet available (though it will be pending the availability of a functioning emulator). * exec/loader-aarch64.s (_start): * exec/loader-armeabi.s (_start): * exec/loader-x86.s (_start): * exec/loader-x86_64.s (_start): Displace auxv, environ, and argv to create sufficient space for the provided file name, and copy the file name there. Replace AT_EXECFN to refer to this space.

Fix program execution on Android 15 QPR2 Beta

2025-02-09T04:06:52Z

* exec/trace.c (process_vm_readv, process_vm_writev): New function pointers. Attempt to load them on recent Android systems when `exec' was not linked with a sufficiently up-to-date libc. (read_memory, user_copy): Always use process_vm_readv and process_vm_writev if available. (handle_openat): Write trailing NULL byte of filename to user buffer. (exec_init): Attempt to dlsym process_vm_readv and process_vm_writev.
