From 2d7bb7580ac174127f8ae127ebc4156a91035fc0 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Wed, 3 Dec 2014 02:33:13 -0500 Subject: [PATCH] callback.h:struct host_callback_struct compilation error on Windows hosts. On Windows, a recent gnulib update imported the lstat module, and this caused a remote-sim.c build failure in struct host_callback_struct: In file included from /[...]/gdb/remote-sim.c:34:0: /[...]/gdb/../include/gdb/callback.h:93:9: error: duplicate member '_stati64' int (*lstat) (host_callback *, const char *, struct stat *); ^ What happens it that gnulib's stat.h makes the following defines: /* Large File Support on native Windows. */ #if 1 # define stat _stati64 #endif and then: #if 1 # if ! 0 /* mingw does not support symlinks, therefore it does not have lstat. But without links, stat does just fine. */ # if !(defined __cplusplus && defined GNULIB_NAMESPACE) # define lstat stat # endif So, the following fields in struct host_callback_struct... int (*stat) (host_callback *, const char *, struct stat *); int (*fstat) (host_callback *, int, struct stat *); int (*lstat) (host_callback *, const char *, struct stat *); ... get translated to... int (*_stati64) (host_callback *, const char *, struct _stati64 *); int (*_fstati64) (host_callback *, int, struct _stati64 *); int (*_stati64) (host_callback *, const char *, struct _stati64 *); ... which causes two fields to have the same name. This patch fixes the issue by renaming the stat-related fields by adding a "to_" prefix, similar to what is done in GDB's target_ops vector. include/gdb/ChangeLog: * callback.h (struct host_callback_struct) : Renamed from "stat". : Renamed from "fstat". : Renamed from "lstat". sim/common/ChangeLog: * sim-io.c (sim_io_stat, sim_io_fstat): Adjust calls to "stat" and "fstat" callbacks by calls to "to_stat" and "to_fstat" (resp) callbacks following renaming in callback.h. * syscall.c (cb_syscall): Likewise.
