These do not provide the lstat(2) or ftruncate(2) functions. truncate(2) is not implemented in older mingw releases. Windows doesn't have symbolic links, so we use stat in place of lstat. For the missing truncate functions we just fail. Applied to csl-arm-20050325-branch. Ok for mainline? Paul 2005-04-29 Paul Brook * common/callback.c (PIPE_BUF): Provide default refinition. (os_lstat): Use stat if lstat is not available on the host. (os_ftruncate): Return EINVAL if not available on the host. (os_truncate): Ditto. * common/configure.ac: Check for lstat, truncate and ftruncate. * common/configure: Regenerate. * common/config.in: Regenerate. --Boundary-00=_TckcCP+jdQkKLF/ Content-Type: text/x-diff; charset="us-ascii"; name="patch.gdb_simhost" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="patch.gdb_simhost" Content-length: 2136 Index: sim/common/callback.c =================================================================== RCS file: /var/cvsroot/src-cvs/src/sim/common/callback.c,v retrieving revision 1.16 diff -u -p -r1.16 callback.c --- sim/common/callback.c 21 Feb 2005 21:59:54 -0000 1.16 +++ sim/common/callback.c 28 Apr 2005 15:01:39 -0000 @@ -60,6 +60,10 @@ #include #endif +#ifndef PIPE_BUF +#define PIPE_BUF 512 +#endif + /* ??? sim_cb_printf should be cb_printf, but until the callback support is broken out of the simulator directory, these are here to not require sim-utils.h. */ @@ -577,7 +581,11 @@ os_lstat (p, file, buf) struct stat *buf; { /* NOTE: hpn/2004-12-12: Same issue here as with os_fstat. */ +#ifdef HAVE_LSTAT return wrap (p, lstat (file, buf)); +#else + return wrap (p, stat (file, buf)); +#endif } static int @@ -596,7 +604,12 @@ os_ftruncate (p, fd, len) } if (result) return result; +#ifdef HAVE_FTRUNCATE result = wrap (p, ftruncate (fdmap (p, fd), len)); +#else + p->last_errno = EINVAL; + result = -1; +#endif return result; } @@ -606,7 +619,12 @@ os_truncate (p, file, len) const char *file; long len; { +#ifdef HAVE_TRUNCATE return wrap (p, truncate (file, len)); +#else + p->last_errno = EINVAL; + return -1; +#endif } static int Index: sim/common/configure.ac =================================================================== RCS file: /var/cvsroot/src-cvs/src/sim/common/configure.ac,v retrieving revision 1.2 diff -u -p -r1.2 configure.ac --- sim/common/configure.ac 14 Jan 2005 20:05:40 -0000 1.2 +++ sim/common/configure.ac 28 Apr 2005 15:02:29 -0000 @@ -37,7 +37,7 @@ AC_SUBST(TARGET_SUBDIR) # These aren't all needed yet, but will be eventually.
