From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx> The s64ilp32 uses 64bit compiler, so it could support “Tetra Integer” mode, which represents a sixteen-byte (128) integer. It's the first 32BIT linux support TImode :) Signed-off-by: Guo Ren <guoren@xxxxxxxxxxxxxxxxx> Signed-off-by: Guo Ren <guoren@xxxxxxxxxx> --- arch/riscv/Kconfig | 1 + arch/riscv/lib/Makefile | 1 + 2 files changed, 2 insertions(+) diff --git a/arch/riscv/Kconfig b/arch/riscv/Kconfig index 33fe624ef6d3..e0c3dee68510 100644 --- a/arch/riscv/Kconfig +++ b/arch/riscv/Kconfig @@ -305,6 +305,7 @@ config ARCH_RV64I config ARCH_RV64ILP32 bool "RV64ILP32" depends on NONPORTABLE + select ARCH_SUPPORTS_INT128 if !$(cc-option,$(m64-flag) -D__SIZEOF_INT128__=0) select 32BIT select MMU diff --git a/arch/riscv/lib/Makefile b/arch/riscv/lib/Makefile index 26cb2502ecf8..68af463795e1 100644 --- a/arch/riscv/lib/Makefile +++ b/arch/riscv/lib/Makefile @@ -9,5 +9,6 @@ lib-y += strncmp.o lib-$(CONFIG_MMU) += uaccess.o lib-$(CONFIG_64BIT) += tishift.o lib-$(CONFIG_RISCV_ISA_ZICBOZ) += clear_page.o +lib-$(CONFIG_ARCH_RV64ILP32) += tishift.o obj-$(CONFIG_FUNCTION_ERROR_INJECTION) += error-inject.o -- 2.36.1
