CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC:

General informations

The Linux kernel configuration item CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC:

• prompt:
• type: bool
• depends on: ( CONFIG_TOOLCHAIN_NEEDS_EXPLICIT_ZICSR_ZIFENCEI ) && ( CONFIG_CC_IS_GCC && CONFIG_GCC_VERSION < CONFIG_110300 )
• defined in arch/riscv/Kconfig
• found in Linux kernels: 6.3–6.19, 7.0–7.1, 7.2-rc+HEAD

Help text

Certain versions of GCC do not support zicsr and zifencei via -march. This option causes an older ISA spec compatible with these older versions of GCC to be passed to GAS, which has the same result as passing zicsr and zifencei to -march.
