From 8ad12057c43b2f08be4578b51f8990296646706a Mon Sep 17 00:00:00 2001 From: Grissiom Date: Fri, 11 Jan 2013 15:13:11 +0800 Subject: [PATCH] Newlib: link with libm in default. libm is a frequently used lib. Newlib is compiled with -ffunction-sections in recent GCC tool chains. The linker would just link in the functions that have been referenced. So setting this won't result in bigger text size. --- components/libc/newlib/SConscript | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/components/libc/newlib/SConscript b/components/libc/newlib/SConscript index 28d66bc0f..6516840ad 100644 --- a/components/libc/newlib/SConscript +++ b/components/libc/newlib/SConscript @@ -11,6 +11,12 @@ cwd = GetCurrentDir() src = Glob('*.c') CPPPATH = [cwd] +# link with libm in default. +# libm is a frequently used lib.
