Make sure the BIOS file ends on an aligned boundary.

If it does not, the address to which mkmscimg.py writes the CRC
and the address from which it is read could differ.

Pass -integrated-as to clang.

This avoids misdetection of target assembler by clang.

Switch to -fPIC.
...
Using -fPIC for everything allows to link the MiSoC static libraries
both into static images such as the BIOS as well as
into shared libraries.

Remove useless includes pulled in by libunwind.
...
These aren't used by libunwind in any configuration and
should be also removed in upstream.
2015-07-26 13:12:23 +03:00
f6639c1833
Add libunwind.
2015-07-26 12:59:18 +03:00
24463a168a
Add a stub getenv() implementation.
...
This is not strictly necessary to build libunwind (it can
be built with -DNDEBUG), but it will be handy while it is
debugged.
It can be removed afterwards.
2015-07-26 12:55:52 +03:00
b2710e437c
Add a stub pthread header.
...
The header implements only the pthread rwlock interface, which
never actually locks.
This is necessary to build libunwind.
2015-07-26 12:54:40 +03:00
b5048f6cf1
Add headers for the dynamic linker interface.
...
These are required for libunwind to discover
the exception frame headers.
2015-07-26 12:53:18 +03:00
7a9975ab5a
Add a stub C++ standard library.
...
This is necessary to build libunwind.
2015-07-26 12:49:21 +03:00

This is taken from glibc. Only PRI* definitions are imported;
functions are not.

common.mak: Pass -fexceptions to clang and clang++.
...
This results in generation of .eh_frame sections. These sections
can be discarded during final linking, or included if exception
handling is desired. For exception handling to work, all sources
must be built with -fexceptions.
2015-07-26 03:30:21 +03:00
69c2a705bf
common.mak: use clang/clang++ to compile C/C++ sources.
...
Note that -integrated-as is not active by default on OR1K,
so we're still shelling out to binutils to assemble.
It is not yet possible to build everything using -integrated-as.
2015-07-26 03:28:37 +03:00

common.mak: remove RANLIB.
...
`ranlib` is not necessary on any system we can possibly build for,
as it is superseded by `ar s` for the last ten years or so (at least).
Thus, change ar invocations to `ar crs`, also removing a `l` flag
that is ignored by binutils.
2015-07-26 03:20:23 +03:00
f500b906e6
common.mak: remove AS.
...
$(AS) was never used: $(assemble) invokes the C compiler instead.
In case of LLVM, this will allow us to consistently use the LLVM
internal assembler for both inline assembly in C and assembly
sources; so, avoid ever invoking binutils as explicitly.

uart.c: rx overflow fix and tx simplification
...
* fixes the clearing of the rx ringbuffer on rx-overflow
* removes tx_level and tx_cts by restricting the ringbuffer
to at least one slot empty
* agnostic of the details of the tx irq: works for uarts that
generate tx interrupts on !tx-full or on tx-empty.
* only rx_produce and tx_consume need to be volatile

bios: add romboot
...
When firmware is small enough, it can be interesting to run code from an embedded blockram memory (faster and not impacted by memory controller activity).
It can also be a fallback option in case boot from flash failed.
To use this, define ROM_BOOT_ADDRESS and initialize the blockram with the firmware data.
