According to the Single UNIX Specification, Version 2 that's where
those macros should be defined. This fixes the libiconv port.
This also fixes some (but not all) build errors for the diffutils and nano ports.
GCC installs a fixed version of the <limits.h> header as per https://gcc.gnu.org/onlinedocs/gcc/Fixed-Headers.html.
The fixed header doesn't include the target's <limits.h> which in turn means that some definitions (such as PATH_MAX)
aren't available. This change requires rebuilding the toolchain (Toolchain/BuildIt.sh).
This fixes the flatbuffers port.
The commit also removes some non-standard defines (U*_MIN) which don't appear to be used
anywhere. By definition they're always 0 though so they're not strictly necessary.
According to the Single UNIX Specification, Version 2 the <arpa/inet.h>
header may optionally include <netinet/in.h> and <inttypes.h>. This
helps with porting software like c-ray that expects this to be the case.
This commit makes the user-facing StdLibExtras templates and utilities
arguably more nice-looking by removing the need to reach into the
wrapper structs generated by them to get the value/type needed.
The C++ standard library had to invent `_v` and `_t` variants (likely
because of backwards compat), but we don't need to cater to any codebase
except our own, so might as well have good things for free. :^)
I dont know why we do a fast path in the Kernel, but not in Userspace
Also simplified the byte explosion in memset to "explode_byte"
it even seemed so, that we missed the highest byte when memseting something
They are the same as strtol() and strtoul() but if there is
overflow/underflow then the maximum integer val/lower integer
val/maximum uint val will be returned while also setting errno to
ERANGE.
Previously, `vsscanf()` would crash whenever it encountered a width
specification. Now, it consumes the width specification but does not
yet do anything with it.
...for 'long long' and 'unsigned long long', instead of reading them as
'long's and 'unsigned long's.
Also add a test for values that can only fit in (unsigned) long long.
Fixes#6096.
This was a regression from the 64-bit off_t changes.
When dropping buffered data after a flush, we would subtract the
buffered amount from zero to get the seek offset. This didn't work
right since the subtraction was done with a 32-bit size_t and we
ended up with e.g (i64)0xfffffffc as the offset.
Fixes#6003.
Added a dummy TIOCSTI ioctl placeholder. This is a dangerous ioctl that
can be used to inject input into a tty. Added for compatibility. Always
fails with EIO.
These simply use StringBuilder::appendvf() internally which is not
optimal in terms of heap allocations, but simple enough and I don't
think they are performance sensitive functions anyway.
Previously, libc.a contained undefined symbols from ssp and libsystem,
which caused static compilation to fail.
We now generate libc.a with a custom CMake rule that combines all
object files from libc, ssp and libsystem to form libc.a
Closes#5758.
