2019-04-03 _exit() always does move 1,%1,; ta 0
2019-04-03 examples/trap-budget: Makefile fixup
---------------- 2.0.6 ------------------------------------------
2019-03-19 Relocated SVT tables .rodata to simplify ROM resident
booting on GR716.
- Does not affect MVT operation
- Does not affect SVT operation when linking program to RAM.
2019-03-18 Added memory scrubber (MEMSCRUB) driver
2019-03-15 examples/mkprom-hello updated to include mkprom -freq option.
2019-03-05 Updated GR716 APBUART init behavior: When -qbsp=gr716
is used, the APBUART is NOT initialized if UART debug
forwarding is enabled. This is determined based on the
The behavior is described in BCC User's Manual, section 7.4.2.
Custom UART initialization behavior can be defined
in the application by implementing a function named
__bcc_con_init(). See the BCC User's Manual for more

2019-02-07 Added I2C master driver
2019-02-01 Added clock gating unit driver
2019-01-31 Updated GR716 static Plug&Play information
2019-01-14 Do not distribute libg.a and libg_nano.a
---------------- 2.0.5 ------------------------------------------
2018-12-17 New peripheral drivers for BCC:
- SpaceWire packet driver (GRSPW)
- GR1553 (bus controller, remote terminal, bus monitor)
* Documentation is available in the BCC User's Manual, chapter
named "Device driver reference".
* Header files (C API) are installed in
* Examples are installed in
2018-12-03 ambapp_ids.h has been updated and is now generated from GRLIB
2018-11-23 Added example on how to measure time budgets:
- window_overflow and window_underflow trap handlers
- interrupt disable and interrupt enable
The example is installed in src/examples/trap-budget.
2018-11-20 SPI driver updated with improved slave select control. Added:
- automatic slave select
- clock gap and automatic slave select during gap
- automatic slave select delay (ASELDEL)
- configuring "ignore SPISEL input" functionality
2018-11-20 Added bcc_timer_tick_init_period(uint32_t usec_per_tick) which
is similar to bcc_timer_tick_init() and takes a parameter
specifying number of microseconds per tick.
2018-11-14 The interrupt controller timestamp API now has the control
and access functions as inline C functions. No API change.
2018-11-08 Improved interrupt disable performance. The functions
bcc_int_disable() and bcc_int_enable() now inlines the trap
instruction. For BPS:s supporting partial write PSR, the
PSR is updated inline without taking the trap. No API change.
---------------- 2.0.4 ------------------------------------------
2018-10-31 Fixed an issue with GDB on Windows printing "socket: No error".
2018-10-23 Fixed an issue with probing the base address
for IRQ(A)MP interrupt controllers. Only affects applications
where the CPU has been preassigned a non-zero interrupt
controller base.
2018-09-27 Added software scrub example: AHBSTAT is used to detect
correctable errors, which are corrected by performing
atomic write. The example is installed in src/examples/swscrub.
---------------- 2.0.3 ------------------------------------------
2018-09-20 argc and argv parameters to main can be set at link or
load time via __bcc_argc and __bcc_argvp. See the BCC User's
Manual section named "Parameters to main()".
2018-09-20 ambapp: The user function "fn" given to ambapp_visit() has got
an updated definition for the "depth" parameter: the first
bridge depth is 0 and the depth increments with one for each
recursed bridge.
2018-09-19 ambapp scan now recurses into buses behind L2CACHE and GRIOMMU.
2018-09-18 struct ambapp_{ahb,apb}_info now has an entry fields pointing
to the corresponding Plug&Play configuration record.
2018-09-18 Fixed ambapp.h AHB membar mask: a disabled AHB memory bank now
has mask 0 in the amba_ahb->mask field.
2018-09-13 Added interrupt timestamp API. See
<bcc/timestamp.h> and the bcc_timestamp_* functions in the
BCC User's Manual. An example using the interrupt timestamp
API is available in src/examples/timestamp.
2018-09-11 Availability of IRQMP interrupt remap support is probed by
the leon3 BSP. It is known at link-time for the other BSP:s.
2018-09-10 Added driver library for programming GRLIB peripherals.
Provided as target library and in source code. See the
"Device drivers reference" in the BCC User's Manual.
2018-08-29 sparc-gaisler-elf-clang uses dwarf 2 debug by default.
2018-08-29 Added support for libatomic. This means that programs using the
<stdatomic.h> interface should link, independent of hardware
support for atomic instructions. (Note however that BCC is
still single-threaded.)
2018-08-27 Cleaned up the "ampmsg" example.
2018-04-17 Added example on how to program flash memories configured in
32-bit data + 7 bit BCH. See src/examples/flash32
2018-03-05 Make sure CLOCKS_PER_SEC is 1000000.
2018-01-05 GCC is compiled with support for link-time optimization.
Link-time optimization is activated with the GCC -flto option.
2018-01-04 Relaxed LLVM host requirements. (Linux-3.5.x, glibc-2.15 or
---------------- 2.0.2 ------------------------------------------
2017-12-15 Updated examples/gr716_romres to use SVT tables in .rodata
instead of .data. This is because .data is not ready at reset trap time.
2017-12-15 Moved SVT lookup-tables to libbcc.a so application can override
them. Useful for some ROM resident applications.
2017-12-15 Added functions for LEON2/LEON3/LEON4 cache control register access:
bcc_set_ccr() and bcc_get_ccr(). Bit definitions are available in <bcc/leon.h>
2017-12-15 Added linkcmds-any for linking application to any address,
overriding BSP knowledge of memory regions. Useful for
memory controllers mapped to non-nominal locations and
executing RAM image from MRAM.
2017-12-14 Updated multilib definitions for the binary distribution
(GCC version). See
* BCC User's Manual, Appendix A
and for details:
* $ sparc-gaisler-elf-gcc -print-multi-lib
2017-12-14 Upgraded GCC to version 7.2.0. The major user level changes
for this compiler upgrade is the addition of the following
GCC compiler options:
These new options select appropriate code generation for
respective LEON components and are described in the BCC
User's Manual. The Appendix named "Recommended GCC options
for LEON systems" has also been updated to reflect the options.
With the upgrade to GCC 7.2.0, BCC version 2.0.2 adds
workarounds for the following techincal notes in addition
to the ones already available in earlier versions.
- GRLIB-TN-0010
- GRLIB-TN-0011
- GRLIB-TN-0012
- GRLIB-TN-0013
NOTE: The LLVM version of BCC 2.0.2 does currently not
include the workarounds.
For general information on changes in GCC 7.2.0 compared to
GCC 4.9.4, see the corresponding GCC release change notes
2017-06-28 Added example on how to achieve very low interrupt response times by utilising
multiple register windows in FLAT register window model. Described in
2017-06-28 Application is free to use %g6 and %g7 for any purpose. %g5 can
also be used by application if -mflat is not used. See section
"Register usage" in User's Manual.
---------------- 2.0.1 ------------------------------------------
2017-06-16 Allow the application to configure heap memory location and
size. Described in User's Manual section "Heap memory
2017-06-15 Generate and distribute .md5 files with BCC archives.
2017-06-15 Fixed ambapp.h masks (was mask+1).
2017-06-13 Added BCC run-time support and multilibs for GCC -mflat. This
enables the single register window model where the compiler
does not generate save/restore instructions, and eliminates
window overflow/underflow at run-time.
2017-06-13 GCC: Enable -mfix-b2bst with -mfix-ut699. This prevents B2BST
errata sequences in the mfix-ut699 multilibs.
2017-06-13 GCC: Fix B2BST issue in function prologues when using -mflat.
2017-06-09 Do not store %psr on stack at interrupt entry.
2017-06-07 Include clang-format
2017-06-07 Reduce size of LLVM binary archives
