Michal Sieron f2a05e92fa Add missing include to or1k/exception.c 2021-09-16 10:44:09 +02:00
Michal Sieron 3d4a64e112 Update stdio code in libc 
Picolibc now requires to create stdin, stdout and stderr files
ourselves instead of __iob array. Thus changes and renaming
of iob.c to stdio.c

f320a0aa17
added option to select default printf format, so using
picolibc.specs or defining PRINTF_LEVEL is no longer needed.

Michal Sieron ef7b287248 Disable thread local storage (TLS) in picolibc 
It was causing some compilation issues with lm32.
As global errno was enabled anyway, it was easier 
to disable TLS whatsoever.
 2021-09-16 10:43:44 +02:00
Michal Sieron c84105f399 Disable LTO for picolibc and use picolibc.specs 
Use picolibc.specs to specify integer only printf/scanf.

To do that, we need to pass specs file with options to
the linker. With LTO enabled, name mapping was failing,
so LTO is now disabled for picolibc compilation only.

This also means, that exchange.c and arc4random.c no
longer need to be recompiled and added back.

Michal Sieron b960ba0a67 Move stuff out of libbase 
Removed libbase completely and moved remaining files into
libutils, libcomm and libmisc.

Libcomm is place for code used for communicating with other
devices, which doesn't yet live in its own liblite*.

Libutils is code used in multiple places, like crc calculation,
progress bar, memtests.

Libmisc is everything else like sim_debug, which is code for
litex_sim or exception.c for or1k.
