Update #3850
|
|
Current state:
- Basic context initialization and switching code.
- Stubbed console (empty functions).
- Mostly functional linker script (may need tweaks if we ever want to move
away from the large code model (see: CPU_CFLAGS).
- Fully functional boot, by using FreeBSD's bootloader to load RTEMS's ELF for
UEFI-awareness.
In short, the current state with this commit lets us boot, go through the system
initialization functions, and then call user application's Init task too.
Updates #2898.

Port
+ v850 does not have appear to have any optimized bit scan instructions
+ v850 does have single instructions for wap u16 and u32
+ Code path optimization preferences set
+ Add BSP variants for each GCC CPU model flag and a README
- v850e1 variant does not work (fails during BSP initialization)
BSP for GDB v850 Simulator
+ linkcmds matches defaults in GDB simulator with RTEMS mods
+ crt1.c added from v850 newlib port for __main()
+ BSP exits cleanly
+ printk and console I/O work
+ uses clock tick from IDLE task
+ Tests not requiring real clock ISR work
Documentation
+ CPU Supplment chapter for v850 added

The XDR library has a problem on architectures with short enums like the
default ARM EABI. Short enums means that the size of the enum type is
variable and the smallest integer type to hold all enum values will be
selected. For many enums this is char. The XDR library uses int32_t
for enum_t. There are several evil casts from an enum type to enum_t
which leads to invalid memory accesses on short enum architectures. A
workaround is to add appropriate dummy enum values.

|
* librpc/src/xdr/xdr_mem.c (xdr_memcreate):
Cast addr to uintptr_t instead of size_t.
|
|
* librpc/src/xdr/xdr_mem.c: Cosmetics from freebsd.
|
|
* librpc/src/rpc/clnt_udp.c, librpc/src/xdr/xdr_mem.c:
Use [u]intptr_t instead of [u_]long for better 16bit compliance.

|
|
|
* librpc/src/xdr/xdr_float.c: Change detection logic for h8300.
|
|
* librpc/src/xdr/xdr_float.c: M32C has no native float but GCC soft
float should be IEEE format.
|
|
* configure.ac, librpc/src/xdr/xdr_float.c, score/cpu/Makefile.am: Add
Lattice Mico32 support.
|
|
* librpc/src/xdr/xdr_float.c: Add M32C, M32R, and Blackfin.

That BSP now has a stub clock driver so the tests can link even
if they won't execute. A handful of Makefiles had to be updated
and we had to account for printk.c being a shared file now.
