* exec.c [! EXECDATA_STREAM] (prepare_stream): Replace no-op with real function to initialize map_* members to zero.
2000-03-132000-03-13 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* priv.h (EXECDATA_STREAM): Define this only #ifdef BFD. The non-BFD exec server is now completely independent of stdio magic; it uses only those interfaces documented in the C library manual, which are provided both by old GNU stdio and by GNU libio. Resurrecting the BFD exec server will require using magic again, for which libio-specific magic needs to be written.

* priv.h (EXECDATA_STREAM): New macro, always defined for now. (struct execdata) [! EXECDATA_STREAM]: Add members map_buffer, map_bsize, map_fsize, map_filepos in place of stream. (map_buffer, map_filepos, map_set_fsize): New macros for accessing those or stream. [! EXECDATA_STREAM] (map_fsize, map_vsize): Define using new members. * exec.c (map): Rewritten purely using those accessor macros. (input_room): Set the __target, __bufp, __error, and __eof members, which are no longer set by map. [! EXECDATA_STREAM] (prepare_stream, prepare_in_memory): Make no-ops. (input_room, close_exec_stream, fake_seek, prepare_stream, prepare_in_memory): Conditionalize these defns on [EXECDATA_STREAM]. (load_section): Always use map instead of stdio. Replace bcopy with memcpy. (check_gzip: zipread): Rewrite using map instead of stdio. (check_bzip2: zipread): Likewise.

* exec.c (map): Made global. * priv.h: Declare it. (map_fsize, map_vsize): New macros for accessing state set up by map. * hashexec.c (check_hashbang): Use map and copying operations rather than stdio to extract the first line from the file. Move finish call to immediately after reading the line.

Move finish call to immediately after reading the line. * exec.c (map): If E->file_data is set, diagnose EOF before going to direct io_read. (prepare_in_memory): New function, broken out of check_gzip before last change. (check_gzip, check_bzip2): Use it.

* exec.c (prepare_stream): New function, broken out of prepare. (prepare): Call it. [_STDIO_USES_IOSTREAM]: Do #error if this is defined. (map, input_room, close_exec_stream, fake_seek, prepare_stream): Conditionalize all these definitions on [! _STDIO_USES_IOSTREAM]. Only map and prepare_stream are called from elsewhere in the code. (check_gzip): Don't reinitialize E->stream, since it will in fact not be used again. (check_bzip2): Likewise.

* hostarch.c (elf_machine_matches_host): Don't recognize EM_486, since newer <elf.h>'s don't define it any more.

* hashexec.c (check_hashbang: user_fd): Add a user ref to DTABLE[FD] send right, because caller (hurd_file_name_lookup internals) will consume one. * hashexec.c (check_hashbang): When dealloc'ing DTABLE ports, optimize out syscall for null ports.

* hostarch.c (mach_host_elf_machine): Replaced with ... (elf_machine_matches_host): New function. Instead of returning an ELF EM_* code, take one and check if it matches the host; operate only on mach_host_self(), cache results, Grok CPU_TYPE_{I486,PENTIUM,PENTIUMPRO} to accept EM_386 or EM_486. Grok POWERPC, ALPHA, HPPA types. * exec.c (check_elf): Call elf_machine_matches_host instead of comparing against elf_machine. (load_section): #if 0 out no-op code that uses elf_machine. * priv.h (elf_machine_matches_host): Declare it. (elf_machine, mach_host_elf_machine): Remove decls. * main.c (main) [!BFD]: Don't call mach_host_elf_machine. (elf_machine): Variable removed.
