.long in RISC-V assembly is 4 bytes, while the address in riscv64
is 8 bytes (.quad). Moreover, RTEMS' libdl increases the symbols
pointer by sizeof(long) in C when iterating over global symbols.
- Provide support to list the compilers and assemblers used to build
an executable.
- List the machine flags showing which flags are common and which are
not.
Add any weak symbols that have been linked into the base image to the
global symbol table. A weak symbol is global when view viewed from
a dynamically loaded module.
Closes#2704.
Limit the compilers used to gcc and clang. Clang has not been tested.
Users with MSVC install does not need to remove now.
Force the os.sep path to the standard '\\' on Windows. The MSYS2 python
sets it to '/' for internal project reasons. Doing this does cause waf
problems when running configure so only do this for the build target.
Closes#2583.
On certain targets (e.g. PowerPC) global data below a certain threshold
(e.g. 8 bytes) may resided in a special memory area, the small-data
area. This allows more efficient load/store operations. Placing such
data into the wrong section (e.g. .rodata) leads to relocation errors
during link-time. See test program libtests/dl02 in the RTEMS
testsuite. Using an array of unspecified size prevents that the
compiler assumes that a certain variable is in the small-data area.
Support a top level VERSION file that defines an RTEMS release.
Fix the install of the python modules including thertems-test.
Update the git python module to the RSB version. Fix the options to
not call clean and to call dirty.
Update the version python module.
Fix the rtld C++ support to the VERSION file and the top level waf
script.
Logging to a file requires a 'trace' lock model be used. The 'trace'
lock model holds the lock for the entire trace time, for example
the entry or exit tracing.
Move the options to a section so an option can be a single line. This
gives the user the ability to localise specific configurations in a
top level configuration file.
Provide support for names, enables and triggers. Names is an array of
names of the trace functions. The table is sorted and you can use an
index to reference the trace function. There is a @FUNC_INDEX@ macro
that is replaced with the trace function's index. Enables is a bitmap
of default trace enabled states for all trace functions. Triggers is
a bitmap of default triggers bit states for each trace function.
Generators can use these bitmaps to control functionality.
Currently the bitmaps are const but a generator option can be added
to disable the const and allow the capture engine access to update
the bitmaps.
