The ARM C++ exception ABI uses an address ordered index table to
locate the correct frame data and this requires the EXIDX sections are
loaded in the order the order the matching text is loaded.
The EXIDX sections set the SHF_LINK_ORDER flag and link field. This patch
adds support to load those flagged sections in the linked-to section
order.
Updates #2955.
Closes#2959
Set CPU_ENABLE_ROBUST_THREAD_DISPATCH to TRUE. In this case the
interrupts are always enabled during a context switch even after
interrupt processing (see #2751). Remove the CPSR from the context
control since it contains only volatile bits.
Close#2954.
Adding modified FreeBSD headers to synchronize RTEMS termios with
FreeBSD. Modify termios to support dedicated input and output baud for
termios structure. Updated BSPs to use dedicated input and output baud
in termios structure. Updated tools to use dedicated input and output
baud in termios structure. Updated termios testsuites to use dedicated
input and output baud in termios structure.
Close#2897.
Remove forced overwrite which leads to file data corruption. The logic
to determine a forced overwrite was fundamentally broken. For simplity,
disable this feature.
Update #2622.
It is all right in case the result uses the full destination buffer.
Without this fix the handling of a maximum 8.3 short file name is
broken.
Update #2928.
Perform a context-dependent deferred location release to avoid a
deadlock on the file system instance locks, for example during a
chdir().
Update #2936.
Check that no ask help request is registered during unblock and yield
scheduler operations. There is no need to ask for help if a scheduled
thread yields, since this is already covered by the pre-emption
detection.
Update #2556.
The second FAT entry contains a bit to indicate if the FAT32 filesystem
is not dirty and a bit to indicate if there was no IO error. Set both
bits for a fresh filesystem. This prevents a warning if mounted on
Windows.
Close#2913.
Currently only blocking read/write operations are implemented. A
blocking write must transfer at least one character. It should not wait
for the device for the second character and so on.
Close#2917.
Call the receive callback in case a read will succeed without to block.
This enables the use of the receive callback for a poll() and select()
support. Increase raw input buffer size to allow buffering of one line.
Close#2916.
In case carriage return characters should be ignored in the input
(IGNCR), then drop them early before they reach the raw input buffer.
This makes it easier to calculate the content size of the raw input
buffer.
This function may be used to do a two-step interrupt processing. The
first step is done in interrupt context which calls this function. The
second step is then done in the context of the interrupt server.
