* Remove the code duplication in tun_net_receive_tap and remove the unused filep field
* Shouldn't return -EBUSY in tun_write. Let the caller wait until the write buffer free
* Handle that write buffer is ready first correctly in tun_read
* Remove the unused tun_ipv6multicast
If SMP is enabled this function will return the number of the CPU that the thread is running on. This is non-standard but follows GLIBC if __GNU_SOURCE is enabled. The returned CPU number is, however, worthless since it returns the CPU number of the CPU that was executing the task when the function was called. The application can never know the true CPU number of the CPU tht it is running on since that value is volatile and change change at any time.
1. Remove the unused and unimplemented ipv6_chksum declaration
2. Update NET_ARCH_CHKSUM description to align with the implementation
3. Declare all checksum function prototype regardless CONFIG_NET_ARCH_CHKSUM
4. Remove the CONFIG_NET_ARCH_CHKSUM guard for tcp_ipv[4|6]_chksum

sim: Prefix symbols with _ for non-ELF
Namely for Mach-O. Leave __CYGWIN__ case as it is.
* Serial Fixed interrupt storm
The target would randomly hang in the serial isr.
The priv->ie and the hardware were inconsistent.
The isr used the priv->ie to gate offloading
the RX data. Bang! Hung.
imxrt_disableuartint(priv, &ie);
ret = imxrt_setup(dev);
/* Restore the interrupt state */
imxrt_restoreuartint(priv, ie);
interrupt-> Of no return
priv->ie = ie;
On a fast cpu with FIFO, this will not work
with out proper protections.
* Serial: Conditionally enable 9 bit mode
* armv7-mi/mpu.hi: Restructure API
Preserve the existing API and enabled better granualriy on
setting.
* Enable MPU for non protected builds to set cache
* mpuinit use symbolic values for addresses
* Allow DTCM on HEAP
* allocateheap Fix Coding style
* ld doesn't have --start-groupi/--end-group things. As far as I know,
it works that way by default.
* objcopy with Mach-O support is not widely available.
(GNU binutils seem to claim the support but it didn't actually work
for me. llvm-objcopy --redefine-syms explicitly rejects Mach-O.)
Instead, use -unexported_symbols_list linker flag to hide symbols
to avoid conflicts with host symbols.
It seems that "ld -r" on macOS doesn't include objects from
libraries for common symbols. Because of that, sim build
ends up with undefined references to globals like g_binfmts
and g_mmheap.
@(#)PROGRAM:ld PROJECT:ld64-530
BUILD 18:57:17 Dec 13 2019
configured to support archs: armv6 armv7 armv7s arm64 arm64e arm64_32 i386 x86_64 x86_64h armv6m armv7k armv7m armv7em
LTO support using: LLVM version 11.0.0, (clang-1100.0.33.17) (static support for 23, runtime is 23)
TAPI support using: Apple TAPI version 11.0.0 (tapi-1100.0.11)
The recent x86-64 convention requires 16-byte alignment before
(not after) calling a function.
This fixes snprintf crash I observed on macOS while saving XMM registers.
Namely this changes HOSTOS for macOS from "Other" to "Darwin".
Also, suppress the following harmless messages during a "make":
(Missing redirect in tools/Makefile.host)
uname: illegal option -- o
usage: uname [-amnprsv]
Consider junk.c for example:
/****************************************************************************
* xx
****************************************************************************/
/****************************************************************************
* Private Types
****************************************************************************/
struct foo_s
{
int bar;
};
/****************************************************************************
* Public Functions
****************************************************************************/
int dofoo(int barin)
{
barout = barin;
return barout;
}
nxstyle not detects these problems:
$ tools/nxstyle.exe junk.c
junk.c:11:0: error: Blank line before opening left brace
junk.c:21:0: error: Blank line before opening left brace
