I did not null terminate short strndup copies :D
2025-01-28 22:40:06 +02:00
Bananymous 48eca3d031 LibC: Make libc usable with tcc
tcc does not provide its own stdint.h but defines everything in
stddef.h. Also tcc does not support [[noreturn]] attribute syntax.

Bananymous cbe3f2a4ac BuildSystem: Cleanup and fix cmake files
I now set library SONAME so i don't have to build them in build root.

Creating font now makes sure the install directory exists. This allows
building using make files.

LibC now links agains ligcc

Bananymous 60bffb5f49 LibC: Implement `clock` in terms of `clock_gettime`

CLOCK_PROCESS_CPUTIME_ID.

Bananymous 766b8cd62e LibC: Fix stdio FILE operations
Mixing read/write/ungetc was broken. This mostly fixes everything. There
might still be some problems that have to be fixed
2025-01-16 14:57:58 +02:00
Bananymous 72059a9441 LibC: Redefine SEEK_* macros to match common systems
some ports written in assembly seem to depend on this
2025-01-14 22:52:13 +02:00
Bananymous ebecbb69ec LibC: Implement some mem* and str* functions in assembly
This made them a lot faster on modern cpus with optimized rep stos and
rep movs
2025-01-14 22:50:46 +02:00
Bananymous 14c70c5cc8 LibC: Make mem* and str* functions weak symbols

providing an general implementation
2025-01-14 18:36:54 +02:00
Bananymous d62a67502e LibC: Remove global -fno-tree-loop-distribute-patterns flag
This is only really needed for string.cpp where mem* and str* functions
are defined
2025-01-14 18:35:33 +02:00
Bananymous 4b2c303873 LibC: Add weak_alias header that defines a weak_alias macro 2025-01-14 18:33:57 +02:00
Bananymous 8c45249c06 LibC: Remove stdint.h as toolchain provides one
I have no idea why i even had this written, it was just containing
compiler macros
2024-12-30 06:26:17 +02:00
Bananymous 581caff638 BuildSystem: Install base sysroot only once
Base sysroot is not only installed when creating the syroot directory
for the first time. To get it installed again, you have to either delete
the old sysroot diretory or run clean target

This makes it so its actually possible to edit files specified in the
base sysroot without random hacks.

Bananymous 415b20f884 LibC: Remove errno EEXISTS
I don't know why I had added this. It doesn't seem to be a thing on
either POSIX or linux. This was literally equivalent to EXIST

Bananymous 12bc7480e0 LibC: Implement _Exit
This just calls _exit as POSIX says they can be equivalent
2024-11-08 02:52:12 +02:00
Bananymous 92862fdf39 LibC: Implement nan{,f,l} as functions
One port was using function pointers to these functions so macros don't
work.

Bananymous a356d90445 LibC: Fix libc compilation for 32 bit target 2024-11-04 10:51:31 +02:00
Bananymous f4be37700f Kernel/userspace: rework floating point math
SSE is now unconditionally enabled any where and most of math.h is now
actually implemented. using __builtin_<func> lead to many hangs where
the builtin function would just call itself.
2024-11-03 20:28:15 +02:00
Bananymous 2464fccadd LibC: Fix *scanf consuming extra characters 2024-10-19 12:43:23 +03:00
Bananymous 88b8ca5b29 LibC: Fix some string functions
I was not casting some required values to char or handling length of
zero
2024-10-13 22:04:08 +03:00
Bananymous fdddb556ae LibC: Implement system() more properly
Old implementation did not ignore and block needed signals
2024-10-13 22:03:15 +03:00
Bananymous e4982a1a5c LibC: Fix printf with alternate format and zero values 2024-09-26 15:25:16 +03:00
Bananymous 4e9f39384a LibC: Initialize libc only once
This was breaking stuff with dynamic loader initializing libc and main
executable reinitializing it later :D

2024-09-17 16:16:47 +03:00
Bananymous 7177da7d62 LibC: Implement dummy get_rusage
One port seems to use this function. This dummy just reports no used CPU
time for current process nor children
2024-09-17 15:59:22 +03:00
Bananymous d88ee5c9ee Kernel/LibC: Implement `creat` with `open`
This allows getting rid of unnecessary SYS_CREATE. Directory creation
still has its own syscall, but I could combine it with SYS_OPEN also.
2024-09-17 15:55:53 +03:00
Bananymous 467ac6c365 Kernel/LibC: Implement SOCK_CLOEXEC and SOCK_NONBLOCK

Bananymous 500f774b7f LibC: Add a lot of stub implementations for different libc functions
some ports want to link against these, but they are not ever called
based on simple testing

This patch adds stubs for
- openlog
- syslog
- getrusage
- mlock
- mprotect
- getpeername
- shutdown
- tzset
- mktime

For some reason some ports include these files even when they detect
that they are not available
2024-08-22 14:47:59 +03:00
Bananymous 25a47f0df3 LibC: Implement ungetc()
I didn't really test this, but I think this implementation does what it
needs to :)

Bananymous a5a097fa4a Kernel/LibC: Add initial pseudo terminal support
This patch implements posix_openpt() and ptsname()

grantpt() and unlockpt() are left in LibC as stubs, as posix_openpt
currently does all of the needed work.

Bananymous ad645f31d0 Kernel/LibC: Add setsid() 2024-08-11 00:58:12 +03:00
