Add TriCore target stubs, and QOM cpu.
Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>
---
v2 -> v3:
- Add cache for PSW_USB bits and psw_write/_read functions.
- Add tricore_feature, set_feature functions and enum of cpu features.
- Remove translate_init.c.
- Move init code from translate_init.c to cpu.c and use type_register instead of a custom list.
- Add cpu model aurix and tc1796, which use set_feature.
- Move tricore_cpu_list to helper.c and now uses GSList.
- Move cpu_tricore_init from translate.c to helper.c and now uses cpu_generic_init (see patch v3[04/15])

Add tcg and cpu model initialization.
Add gen_intermediate_code function.
Activate target in configure and add softmmu config.
Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

v2 -> v3:
- Add initialization for PSW_USB bits as TCG regs.
- Remove cpu_tricore_init from translate.c (see patch v3[01/15])
- Remove translate_init.c (see patch v3[01/15])

Add instructions of SRC opcode format.
Add micro-op generator functions for add, conditional add/sub and shi/shai.
Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>
---
v2 -> v3:
- Remove helper_shac, gen_shac
- Remove len parameter of gen_shaci
- Change gen_shaci to a special case.
- Add gen_calc_psw_* functions to generate the calculation of PSW bits.
- Add gen_add_i32 micro-op generator, that handles PSW bits.
- Replace ADD instructions with gen_add_i32 for PSW bit calculation.
- Change OP_COND to handle PSW bits.
- MOV_A: Remove sign extended loading of const4
- gen_shi: Remove wrong documentation

Not exclusive or, inclusive or. And there's really no need for a helper for this.

No need for the andi if you do as I suggested and only consider the high bit
when reading the value from PSW_AV.

Again, inclusive or.

I strongly suggest that you name this something else, because you've gone and
confused yourself: this only applies to adds in the data registers.

This computation is not overflow, but carry. As I said, see e.g. the ARM port
where we properly compute overflow as
R = A + B
VF = (R ^ A) & ~(A ^ B)
i.e.
tcg_gen_xor_tl(VF, R, A)
tcg_gen_xor_tl(tmp, A, B)
tcg_gen_andc_tl(VF, VF, tmp)
considering only the most significant bit as the overflow.

BTW, this macro substitution isn't going to work well as is, since there are
different overflow computations for addition and subtraction.

You don't need a 64-bit shift here.

Likewise, although that does mean you need to handle the special case of -32.

Note that right shifts can't overflow, since the magnitude always reduces.
I suppose using the 64-bit shift result is a reasonable way to compute left
shift overflow on a 64-bit host. It seems like there's an easier way to
compute this that would be better for 32-bit hosts though...
One way is to adjust the comparisons for prior to the shift. That is,
R >= 0x7fff_ffff
= (A << C) >= 0x7fff_ffff
= A >= (0x7fff_ffff >> C)
Also, using 2 setcond and 1 or is more efficient than 2 movcond with those
constants on most hosts.

No PSW computation here.

- Replace ADD instructions with gen_add_i32 for PSW bit calculation.
- Add gen_sub/mul_i32 for PSW bit calculation
- Replace SUB instructions with gen_sub_i32 for PSW bit calculation.
- Replace MUL instruction with gen_mul_i32s for PSW bit calculation.
- Fix PSW bit calculation in SSOV makro.

This zero-extends r1 and r2; you need to sign-extend in order for your
saturation to work.

This computes neither carry nor overflow.

Overflow computation requires that you compare the high part of the result vs
the sign of the low part of the result. I.e.
overflow = (high != (low >> 31));

Add instructions of SB opcode format.
Add helper call/ret.
Add micro-op generator functions for branches.
Add makro to generate helper functions.

v2 -> v3:
- Fix CDC.COUNT calculation in cdc_increment/_decrement.
- helper_ret/_call now use psw_read/_write.
- helper_ret now stores PSW depending on TRICORE_FEATURE.
- Remove sextract of OPC1_16_SB_CALL insn.

Add instructions of SR opcode format.
Add micro-op generator functions for saturate.
Add helper return from exception (rfe).
Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>
---
v2 -> v3:
- Fix CDC.COUNT calculation in cdc_zero.
- helper_ret now uses psw_write.
- Add missing temp_free to gen_saturate.
- RSUB: replace tcg_gen_subfi_tl with tcg_gen_net_tl.
