From 30bfee2630b960050d1d50cafaab43fc171abc03 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Wed, 21 Feb 2018 14:38:24 -0500 Subject: Remove miscellaneous debris from libio. This patch eliminates a number of #if 0 and #ifdef TODO blocks, macros that are never used, macros that provide portability to substrates that lack basic things like EINVAL and off_t, and other such debris. I preserved IO_DEBUG and CHECK_FILE, even though as far as I can tell IO_DEBUG is never defined and therefore CHECK_FILE never does anything, because it seems like we might actually want to turn it _on_. Installed stripped libraries and executables are unchanged, except, again, that the line number of an assertion changes (this time it's somewhere in fileops.c). * libio/libio.h (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Define here, unconditionally. * libio/iolibio.h (_IO_pos_BAD): Don't define here. * libio/libioP.h: Remove #if 0 blocks. (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Don't define here. (_IO_va_start, COERCE_FILE, MAYBE_SET_EINVAL): Don't define. (CHECK_FILE): Don't use MAYBE_SET_EINVAL or COERCE_FILE. Fix style. * libio/clearerr.c, libio/fputc.c, libio/getchar.c: Assume weak_alias is always defined. * libio/fileops.c, libio/genops.c, libio/oldfileops.c * libio/oldpclose.c, libio/pclose.c, libio/wfileops.c: Remove #if 0 and #ifdef TODO blocks. Assume text_set_element is always defined. * libio/iofdopen.c, libio/iogetdelim.c, libio/oldiofdopen.c Use __set_errno (EINVAL) instead of MAYBE_SET_EINVAL. * libio/tst-mmap-eofsync.c: Make #if 1 block unconditional. --- libio/clearerr.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'libio/clearerr.c') diff --git a/libio/clearerr.c b/libio/clearerr.c index 5d29fc5..77ac552 100644 --- a/libio/clearerr.c +++ b/libio/clearerr.c @@ -27,6 +27,6 @@ clearerr (FILE *fp) _IO_funlockfile (fp); } -#if defined weak_alias && !defined _IO_MTSAFE_IO +#ifndef _IO_MTSAFE_IO weak_alias (clearerr, clearerr_unlocked) #endif -- cgit v1.1
