milescoviello 89bc9d1082 fix(libc): read %i without the C23 binary prefix in the scanf family on Linux
On Linux sscanf, vsscanf, fscanf and sscanf_s hand their conversions to
glibc. Since glibc 2.38, code built as GNU C++ calls the C23 entry
points (__isoc23_vsscanf, __isoc23_vfscanf, __isoc23_sscanf), whose %i
reads a 0b/0B binary prefix. On main,
sscanf("0b101 x", "%i%n%7s", &value, &end, rest) stores value 5 and
end 5 and leaves "x" for the %s; " -0B11" gives -3. TechnicalDebt
records this.

FreeBSD's %i knows only the 0 and 0x prefixes. FreeBSD 11.4
lib/libc/stdio/vfscanf.c, parseint, lines 345-353 and 371-380:

	case '0':
		if (base == 0) {
			base = 8;
			flags |= PFXOK;
		}
	...
	/* letters ok iff hex */
	case 'A': case 'B': case 'C':
	case 'D': case 'E': case 'F':
	case 'a': case 'b': case 'c':
	case 'd': case 'e': case 'f':
		/* no need to fix base here */
		if (base <= 10)
			break;	/* not legal here */

so "0b101" stores 0, consumes the "0" and leaves "b101", as C17 does
and as the strtol family here already does.

With glibc the scanf family now calls __isoc99_vsscanf and
__isoc99_vfscanf, the entry points GNU C++ used before glibc 2.38
(exported since 2.7), which read %i without the binary prefix. Other
hosts keep std::vsscanf and std::vfscanf. The TechnicalDebt entry is
removed.

About

Tool for automatic executables porting to Linux and Windows.

Includes a relinker that converts executable to the target system's native format and implementations of system prx libraries suitable for dynamic linking. No emulation or separate runtime process.

progress map

* System libraries: percentage of the functions known to the project so far (declared in core/libs/prx), not of every PS5 system function. The total grows as more functions are declared.

List of verified games

Dreaming Sarah (2D platformer) runs at a stable 60 fps on a GTX 1050 Ti / i5-7500 3.4GHz.

Unsupported or unexpected states strictly throw std::runtime_error. what() is printed to stderr and the process terminates.

The shader recompiler successfully produces SPIR-V (validated via Spirv-Tools when built with ANYPS5_ENABLE_SPIRV_TOOLS).

Compatibility

See the game compatibility list for tested games and known issues.

Input mapping

SDL-mapped game controllers are supported, including analog sticks and triggers. Keyboard and mouse controls can be configured with an anyps5-input.ini file. See input mapping for the supported devices and configuration format.
