From 5b96251953f0974a23ffaae3ce04781b3a3f23e7 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Tue, 17 Apr 2007 22:24:42 +0000 Subject: Add the EXPERIMENTAL option to show options marked as such. Add the four types of toolchains ct-ng is able to build as EXPERIMENTAL, except for CROSS which *is* functional. Reorder menus accordingly. diff --git a/config/cc.in b/config/cc.in index 18eb559..1412a0f 100644 --- a/config/cc.in +++ b/config/cc.in @@ -38,6 +38,7 @@ config CC_CORE_GCC #config CC_CORE_TCC # bool # prompt "tcc (EXPERIMENTAL)" +# depends on EXPERIMENTAL endchoice @@ -78,6 +79,7 @@ config CC_GCC # bool # prompt "tcc (EXPERIMENTAL)" # select CC_LANG_C +# depends on EXPERIMENTAL endchoice diff --git a/config/config.in b/config/config.in index 76bc8ca..c858b3b 100644 --- a/config/config.in +++ b/config/config.in @@ -1,5 +1,6 @@ source config/global.in source config/target.in +source config/toolchain.in source config/kernel.in source config/binutils.in source config/cc.in diff --git a/config/global.in b/config/global.in index 767ce3a..fe55589 100644 --- a/config/global.in +++ b/config/global.in @@ -2,6 +2,20 @@ menu "Paths and misc options" +config EXPERIMENTAL + bool + prompt "Try features marked as EXPERIMENTAL" + default n + help + If you set this to Y, then you will be able to try very experimental + features. + + Experimental features can be one of: + - working, in which case you should tell me it is! + - buggy, in which case you could try patching and send me the result + - unfinished, in which case you could try hacking it and send me the result + - non-existant, in which case you could also try hacking it in and send the result + config PARALLEL_JOBS int prompt "Number of parallel jobs" diff --git a/config/target.in b/config/target.in index 1c87ff1..27ddc83 100644 --- a/config/target.in +++ b/config/target.in @@ -172,7 +172,7 @@ config ARCH_FLOAT_SW_LIBFLOAT config TARGET_CFLAGS string - prompt "Default target CFLAGS" + prompt "Target CFLAGS" default "" help Used to add specific options when compiling libraries of the toolchain, @@ -183,134 +183,4 @@ config TARGET_CFLAGS Leave blank if you don't know better. -comment "Toolchain options" - -config USE_SYSROOT - bool - prompt "Use sysroot'ed toolchain" - default y - help - Use the 'shinny new' sysroot feature of gcc: libraries split between - prefix/target/sys-root/lib and prefix/target/sys-root/usr/lib - - You definitely want to say 'Y' here.
