Subject: [PATCH 22/40] sim/m32r: Fixes to Linux emulator
Date: Thu, 20 Oct 2022 09:32:27 +0000 [thread overview]
Message-ID: <a3693e7a058878c5a64f39ce0e58c7a2605b3a07.1666258361.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <cover.1666258361.git.research_trasio@irq.a4lg.com>
This commit fixes various M32R Linux emulator issues.
1. Some header files were missing
a. <sys/ioctl.h> for ioctl
b. <sys/fsuid.h> for setfsuid/setfsgid (Linux 1.2 or later)
c. <sys/file.h> for flock (a syscall on Linux 2.0 or later)
d. <sys/sendfile.h> for sendfile (Linux 2.2 or later)
2. syslog function must be called as a syscall rather than POSIX syslog
because we are emulating Linux system calls on the Linux host.
3. ftime function is deprecated but used intentionally.
We have to disable deprecated function warning.
