This will set up - the toolchain so that it supports the SPE ABI extensions. This - mainly targets Freescale e500 processors. - - Setting this option will append "spe" to the end of your target - tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc - configure/build system will know to include SPE ABI support. It - will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS, - and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you - do not need to explicitly add them. - -endchoice diff --git a/config/arch/pru.in b/config/arch/pru.in new file mode 100644 index 0000000..f26dc7a --- /dev/null +++ b/config/arch/pru.in @@ -0,0 +1,8 @@ +# PRU specific config options + +## no-package +## select ARCH_SUPPORTS_8 +## select ARCH_DEFAULT_8 +## +## help The TI PRU core, as defined by: +## help http://bbb.io/pru diff --git a/config/arch/riscv.in b/config/arch/riscv.in new file mode 100644 index 0000000..6b98520 --- /dev/null +++ b/config/arch/riscv.in @@ -0,0 +1,19 @@ +# RISC-V specific config options + +## no-package +## depends on EXPERIMENTAL +## +## select ARCH_SUPPORTS_32 +## select ARCH_SUPPORTS_64 +## select ARCH_DEFAULT_32 +## select ARCH_SUPPORTS_BOTH_MMU +## select ARCH_SUPPORTS_WITH_ABI +## select ARCH_SUPPORTS_WITH_ARCH +## select ARCH_SUPPORTS_WITH_TUNE +## select GCC_REQUIRE_7_or_later +## select BINUTILS_REQUIRE_2_28_or_later +## select GDB_REQUIRE_8_0_or_later if DEBUG_GDB +## select GLIBC_REQUIRE_2_29_or_later if LIBC_GLIBC + +## help The RISC-V architecture, as defined by: +## help http://www.riscv.org/ diff --git a/config/arch/s390.in b/config/arch/s390.in index 00bc879..64107b6 100644 --- a/config/arch/s390.in +++ b/config/arch/s390.in @@ -1,5 +1,6 @@ # s390 specific config options +## no-package ## select ARCH_SUPPORTS_32 ## select ARCH_SUPPORTS_64 ## select ARCH_DEFAULT_32 diff --git a/config/arch/sh.in b/config/arch/sh.in index 60de313..ff2ec14 100644 --- a/config/arch/sh.in +++ b/config/arch/sh.in @@ -1,11 +1,77 @@ # Super-H specific configuration file +## no-package ## select ARCH_SUPPORTS_32 ## select ARCH_DEFAULT_32 -## select ARCH_USE_MMU -## select ARCH_SUPPORTS_BOTH_ENDIAN +## select ARCH_SUPPORTS_BOTH_MMU +## select ARCH_DEFAULT_HAS_MMU +## select ARCH_SUPPORTS_FLAT_FORMAT +## select ARCH_SUPPORTS_EITHER_ENDIAN ## select ARCH_DEFAULT_LE ## select ARCH_REQUIRES_MULTILIB +## select ARCH_SUPPORTS_WITH_ENDIAN ## ## help The Super-H architecture, as defined by: ## help http://www.renesas.com/fmwk.jsp?cnt=superh_family_landing.jsp&fp=/products/mpumcu/superh_family/ + +choice + bool + prompt "Variant" + +# GCC supports both endiannesses even if a specific CPU is selected (so long +# as that CPU can be both BE/LE), but the binutils (or specifically, ld) +# configures for both endiannesses only if sh-*-linux target is selected. +config ARCH_SH_SH + bool + prompt "unspecified" + select ARCH_SUPPORTS_BOTH_ENDIAN + select ARCH_SUPPORTS_WITH_CPU + help + If left unspecified, GCC will determine the set of multilibs to compile automatically + based on selected endianness, FPU mode and OS. + +config ARCH_SH_SH1 + bool + prompt "sh1" + +config ARCH_SH_SH2 + bool + prompt "sh2" + +config ARCH_SH_SH2E + bool + prompt "sh2e" + +config ARCH_SH_SH2A + bool + prompt "sh2a" + +config ARCH_SH_SH3 + bool + prompt "sh3" + +config ARCH_SH_SH3E + bool + prompt "sh3e" + +config ARCH_SH_SH4 + bool + prompt "sh4" + +config ARCH_SH_SH4A + bool + prompt "sh4a" + +endchoice + +config ARCH_SH_VARIANT + string + default "sh" if ARCH_SH_SH + default "sh1" if ARCH_SH_SH1 + default "sh2" if ARCH_SH_SH2 + default "sh2e" if ARCH_SH_SH2E + default "sh2a" if ARCH_SH_SH2A + default "sh3" if ARCH_SH_SH3 + default "sh3e" if ARCH_SH_SH3E + default "sh4" if ARCH_SH_SH4 + default "sh4a" if ARCH_SH_SH4A diff --git a/config/arch/sh.in.2 b/config/arch/sh.in.2 deleted file mode 100644 index 82856ee..0000000 --- a/config/arch/sh.in.2 +++ /dev/null @@ -1,25 +0,0 @@ -# Super-H specific configuration file -
