From 593d33fe334761853890f2f84ed41e7c24051de2 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Fri, 25 Apr 2014 01:52:46 +0200 Subject: [PATCH] MIPS: math-emu: Move various objects into an ar library. ieee754d.o contains only debug code and dp_sqrt.o and sp_sqrt.o contain code which for MIPS I/II/III systems we don't want to link. Again the savings can be considerable for some systems: $ mips-linux-size --totals ieee754d.o dp_sqrt.o sp_sqrt.o text data bss dec hex filename 1624 0 0 1624 658 ieee754d.o 2016 0 0 2016 7e0 dp_sqrt.o 736 0 0 736 2e0 sp_sqrt.o 4376 0 0 4376 1118 (TOTALS) Signed-off-by: Ralf Baechle --- arch/mips/Kbuild | 1 - arch/mips/Makefile | 1 + arch/mips/math-emu/Makefile | 13 +++++++------ 3 files changed, 8 insertions(+), 7 deletions(-) diff --git a/arch/mips/Kbuild b/arch/mips/Kbuild index d2cfe45f332b..cc39966ca63d 100644 --- a/arch/mips/Kbuild +++ b/arch/mips/Kbuild @@ -16,7 +16,6 @@ obj- := $(platform-) obj-y += kernel/ obj-y += mm/ -obj-y += math-emu/ ifdef CONFIG_KVM obj-y += kvm/ diff --git a/arch/mips/Makefile b/arch/mips/Makefile index 1a5b4032cb66..4852ae97e7df 100644 --- a/arch/mips/Makefile +++ b/arch/mips/Makefile @@ -251,6 +251,7 @@ OBJCOPYFLAGS += --remove-section=.reginfo head-y := arch/mips/kernel/head.o libs-y += arch/mips/lib/ +libs-y += arch/mips/math-emu/ # See arch/mips/Kbuild for content of core part of the kernel core-y += arch/mips/ diff --git a/arch/mips/math-emu/Makefile b/arch/mips/math-emu/Makefile index 363ce9bd82ea..016736ed304c 100644 --- a/arch/mips/math-emu/Makefile +++ b/arch/mips/math-emu/Makefile @@ -2,11 +2,12 @@ # Makefile for the Linux/MIPS kernel FPU emulation. # -obj-y := cp1emu.o ieee754d.o ieee754dp.o ieee754sp.o ieee754.o \ - ieee754xcpt.o dp_div.o dp_mul.o dp_sub.o dp_add.o dp_fsp.o \ - dp_cmp.o dp_simple.o dp_tint.o dp_fint.o dp_tlong.o dp_flong.o \ - sp_div.o sp_mul.o sp_sub.o sp_add.o sp_fdp.o sp_cmp.o sp_simple.o \ - sp_tint.o sp_fint.o sp_tlong.o sp_flong.o dp_sqrt.o sp_sqrt.o \ - kernel_linkage.o dsemul.o +obj-y += cp1emu.o ieee754dp.o ieee754sp.o ieee754.o ieee754xcpt.o dp_div.o \ + dp_mul.o dp_sub.o dp_add.o dp_fsp.o dp_cmp.o dp_simple.o dp_tint.o \ + dp_fint.o dp_tlong.o dp_flong.o sp_div.o sp_mul.o sp_sub.o \ + sp_add.o sp_fdp.o sp_cmp.o sp_simple.o sp_tint.o sp_fint.o \ + sp_tlong.o sp_flong.o kernel_linkage.o dsemul.o + +lib-y += ieee754d.o dp_sqrt.o sp_sqrt.o obj-$(CONFIG_DEBUG_FS) += me-debugfs.o -- 2.30.2
