CONFIG_ARC_HAS_ACCL_REGS: Reg Pair ACCL:ACCH (FPU and/or MPY > 6 and/or DSP)

General informations

The Linux kernel configuration item CONFIG_ARC_HAS_ACCL_REGS has multiple definitions:

Reg Pair ACCL:ACCH (FPU and/or MPY > 6 and/or DSP) found in arch/arc/Kconfig

The configuration item CONFIG_ARC_HAS_ACCL_REGS:

• prompt: Reg Pair ACCL:ACCH (FPU and/or MPY > 6 and/or DSP)
• type: bool
• depends on: (none)
• defined in arch/arc/Kconfig
• found in Linux kernels: 5.7–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

Depending on the configuration, CPU can contain accumulator reg-pair (also referred to as r58:r59). These can also be used by gcc as GPR so kernel needs to save/restore per process
