PowerPC: Move -fPIC flag to common place The -fPIC flag belongs with -mrelocatable, move it there. Also change -fPIC to -fpic as this produces smaller binaries. However, currently -mrelocatable promotes -fpic to -fPIC, a fix for this is in upcoming gcc 4.6 or you can apply this small patch to gcc: diff --git a/gcc/config/rs6000/sysv4.h b/gcc/config/rs6000/sysv4.h index 8da8410..e4b8280 100644 --- a/gcc/config/rs6000/sysv4.h +++ b/gcc/config/rs6000/sysv4.h @@ -227,7 +227,8 @@ do { \ } \ \ else if (TARGET_RELOCATABLE) \ - flag_pic = 2; \ + if (!flag_pic) \ + flag_pic = 2; \ } while (0) #ifndef RS6000_BI_ARCH -- Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> 2010-12-06 13:36:46 +00:00			`PLATFORM_RELFLAGS += -meabi`

83xx: Replace CONFIG_MPC83XX with CONFIG_MPC83xx Use the standard lowercase "xx" capitalization that other Freescale architectures use for CPU defines to prevent confusion and errors Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com> 2009-05-22 22:23:24 +00:00			`PLATFORM_CPPFLAGS += -DCONFIG_MPC83xx -DCONFIG_E300 \`
PPC: Use r2 instead of r29 as global data pointer R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de> 2008-02-14 21:43:22 +00:00			`-ffixed-r2 -msoft-float`
