[Qemu-devel] [PATCH v3 00/15] TriCore architecture guest implementation

[Bastian Koppelmann <kbastian@mail.uni-paderborn.de>]

Hi,

my aim is to add Infineon's TriCore architecture to QEMU. This series of patches adds the target stubs, a basic testboard and a softmmu for system mode emulation. Furthermore it adds all the 16 bit long instructions of the architecture grouped by opcode format.

After this series of patches. Another one will follow, which adds a lot of the 32 bit long instructions.

All the best

Bastian

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
    - Add initialization for PSW_USB bits as TCG regs.
    - 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/sub/mul_i32 micro-op generator, that handles PSW bits.
    - Replace ADD/SUB/MUL instructions with gen_add/sub/mul_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
    - Fix PSW bit calculation in SSOV makro.
    - Fix CDC.COUNT calculation in cdc_increment/_decrement/_zero.
    - helper_ret/_call now use psw_read/_write.
    - helper_ret now stores PSW depending on TRICORE_FEATURE.
    - helper_ret now uses psw_write.
    - Add missing temp_free to gen_saturate.
    - RSUB: replace tcg_gen_subfi_tl with tcg_gen_net_tl.
