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_CLANG && CONFIG_CLANG_VERSION < CONFIG_170000 ) || ( CONFIG_CC_IS_GCC && CONFIG_GCC_VERSION < CONFIG_110300 ))
• defined in arch/riscv/Kconfig
• found in Linux kernels: 6.3–6.15

Help text

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