This warning occurs when comparing a signed variable to an unsigned one.
This is frequently an int or ssize_t variable compared to a uint32_t or
size_t. Sometimes the size_t is from a sizeof() use.
This warning indicates the potential for using a local variable which
is not guaranteed to be preserved across a setjmp()/longjmp() pair.
Updates #5364.
This adds a missing text description for an internal error and updates
the spinternalerror02 test to check for the correct end of internal
error definitions.
Most of these warnings were between int or ssize_t and size_t.
In particular, various POSIX system calls like read() and write()
return ssize_t and comparing that value with the sizeof a buffer
is a common source of these warnings. Another common source is
using an int as the iterator in a for loop with the limit being
a size_t.
With the type change, some printf() specifiers needed to change also.

Silences -Werror=unused-parameter warnings in psximfs and psximfs04
tests by explicitly casting the unused argument to void. This fixes
the build on strict compilers.
Added API header OK test in psxtests/psxhdrs
as a part of my work to GSoC 25
note that functions ppoll(), sem_clockwait() and timespec_get()
don't have a prototype yet so the tests will fail. I won't
add them to the libpsxhdrs.yml file until my PR is approved in newlib.
- Extend IMFS and libio headers to define default allocator/deallocator ops
and logic for configuring memfile_ops.
- Update imfs_memfile to use custom allocators for memory blocks.
- Fix imfs_statvfs.f_bfree calculation to respect user-defined ops.
- Add psximfs03 test case to validate custom allocator behavior.
- Refactor psximfs01 to share helper functions with psximfs03.
Updated comments and documentation files across the bsps directory
to replace obsolete references to libbsp with their new locations
in the bsps directory.
Updates #5323
The GCC warning -Wenum-conversion flagged the call to
_Core_message_queue_Submit() as returning a Status_Control
but the caller assigned it to a variable of type rtems_status_code.
The GCC warning -Wenum-conversion flagged assigning the return value
from _Objects_Name_to_id_u32 to an rtems_status_code variable. It
returns a Status_Control value.
Added the implementation of timespec_get() with tests.
The implementation used clock_gettime() as a reference.
The tests used psxtimes01 as a reference.
Updates
rtems/programs/gsoc#69
This change was made to address GCC -Wshift-negative-value.
Shifting a negative value is undefined in the C programming language
because one's and two's complement representations give different
results.
Closes#5385.
This adds a backend for flashdev that simulates a flash device with
adjustable delays to simulate real flash devices and offers
configurable flash parameters. This also migrates the JFFS2
filesystem tests to the flashdev framework and eliminates the
purpose-built simulated flash in the testsuite in favor of a more
generic and widely usable solution.
rtems_message_queue_broadcast() may, under certain circumstances, copy
the message to tasks which were not waiting on the message queue when
the broadcast started, and may copy the message multiple times to the
same task.
This behaviour is, based on discussion in #4804, something that might
not change in the short term, so expose it in the user documentation.
The wording is copied with modifications from an existing internal
requirements note.
Also correct "none-atomic" -> "non-atomic" in said internal requirements
note.
The changes were auto-generated from rtems-central.
Uses the CONFIGURE_MAXIMUM_PRIORITY to set the priority range for
EDF and CBS schedulers under the control of applications.
The default priority behavior is now the same as other schedulers.
The user API to get a task's current priority returns 0 for deadline
driven tasks.
Fixes#5390
GCC generates type limit warnings when comparison is always true or
always false due to the limited range of the data type, This was in a
termios structure. For most of the cases in RTEMS, this was when
a variable of an unsigned type was compared to be < or <= 0.
Address missing field initializer warnings.
These were rtems_extensions_table declarations with initialization.
The initialization was changed to using named fields.
Updates #5325.
Address missing field initializer warnings.
These were rtems_shell_cmd_t or rtems_shell_alias_t declarations
with initialization. The initialization was changed to using named
fields.
Updates #5325.
