The only hand-written asm is the glue to Artworks Render. Update
it to be ABI compliant when building for EABI and force the
alignment of the data in the .bss section (as unaligned rotated
loads are really not a thing).
No functional change for non-EABI builds but, as the stack framing
differs depending on the ABI in use, we can no longer reliably use
fp as the base pointer for on-stack function arguments to
awrender_render. Thus, this has been reworked to use ip as the
pointer instead and to also use r8/r9 to relieve excess register
pressure.
99012dcd introduced a regression that caused builds for all
non-RISC OS platforms to fail. Fix this, ensuring that RISC OS
builds still do the things they need to.
When computing throbber sprite names, ensure the current frame is
in range before using it.
Similarly ensure the buffer size for the temporary URL bar sprite
name is sized such that snprintf has space for the trailing NUL
when formatting it to the output buffer.
Ensure that strings copied using strncpy are NUL terminated.
Additionally, replace use of strncpy entirely where we are writing
into non-indirected OS icon blocks (where an unterminated 12
character long string is perfectly valid).
UnixLib defines ssize_t to be a long int, which forces the
corresponding format string to need to be %ld to avoid compiler
warnings. Making this change uncovered a number of places where
we were using the wrong format specifier entirely (namely
PRIssizet where we meant PRIsizet). Fix these, too.
The new toolchain has a different machine triplet, so update the
things that care about it to work either way.
Remove the expectation that ro-pkg-config exists (it's trivial
and the core buildsystem never used it, so let's have some
consistency).
Determine the location of the zip binary in Makefile.tools, just
like for all the other tooling and stop assuming where it's
installed in the netsurf.zip target.
Replace the fetching and poking around inside the low-level EC
object with appropriate calls to EVP_PKEY_get_(octet|utf8)_string_param()
and add a compatibility layer for old versions of OpenSSL.
Replace the fetching and poking around inside the low-level RSA
object with appropriate calls to EVP_PKEY_get_bn_param() and
add a compatibility layer for old versions of OpenSSL.
If RUfl detects it is running in a Wimp task it will display a
progress meter while scanning fonts. We had this behaviour until
~2017, when it became broken due to the font initialisation being
moved before the call to Wimp_Initialise (because the hotlist
display logic got moved to the treeview, which needs fonts set up)
Move both the font and hotlist initialisation after the call to
Wimp_Initialise to restore the desired behaviour.
Not all runtime library headers declare the first argument to
regexec as being const so don't make our snregexec wrapper do so.
Additionally, make save_complete_import_re static.
