cdd87465 - ARM: vfp: Use undef hook for handling VFP exceptions

Sat, 18 Mar 2023 23:28:35 +0000

ARM: vfp: Use undef hook for handling VFP exceptionsNow that the VFP support code has been reimplemented as a C functionthat takes a struct pt_regs pointer and an opcode, we can use theexisting undef_hook framework to deal with undef exceptions triggered byVFP instructions instead of having special handling in assembler.Reviewed-by: Linus Walleij Signed-off-by: Ard Biesheuvel List of files: /linux-6.15/arch/arm/vfp/Makefile

a6c30873 - ARM: 8989/1: use .fpu assembler directives instead of assembler arguments

Thu, 09 Jul 2020 10:17:36 +0000

ARM: 8989/1: use .fpu assembler directives instead of assembler argumentsExplicit FPU selection has been introduced in commit 1a6be26d5b1a("[ARM] Enable VFP to be built when non-VFP capable CPUs are selected")to make use of assembler mnemonics for VFP instructions.However, clang currently does not support passing assembler flagslike this and errors out with:clang-10: error: the clang compiler does not support '-Wa,-mfpu=softvfp+vfp'Make use of the .fpu assembler directives to select the floating pointhardware selectively. Also use the new unified assembler languagemnemonics. This allows to build these procedures with Clang.Link: https://github.com/ClangBuiltLinux/linux/issues/762Signed-off-by: Stefan Agner Signed-off-by: Russell King List of files: /linux-6.15/arch/arm/vfp/Makefile

35f5a6ac - ARM: 8782/1: vfp: clean up arch/arm/vfp/Makefile

Wed, 18 Jul 2018 01:07:47 +0000

ARM: 8782/1: vfp: clean up arch/arm/vfp/MakefileSince commit 799c43415442 ("kbuild: thin archives make default forall archs"), $(AR) is used instead of $(LD) to combine object files.The following code in arch/arm/vfp/Makefile: LDFLAGS +=--no-warn-mismatch... is no longer used.Also, arch/arm/Makefile already guards arch/arm/vfp/ by a booleansymbol, CONFIG_VFP, like this: core-$(CONFIG_VFP) += arch/arm/vfp/So, $(CONFIG_VFP) is always evaluated to y in arch/arm/vfp/Makefile.There is no point to use pseudo object, vfp.o, which never becomesa module. Add all objects to obj-y directly.Signed-off-by: Masahiro Yamada Signed-off-by: Russell King List of files: /linux-6.15/arch/arm/vfp/Makefile

82b9c18d - ARM: vfp: use -mfloat-abi=soft to build vfp

Sat, 27 Aug 2011 20:09:36 +0000

ARM: vfp: use -mfloat-abi=soft to build vfpDistros are starting to ship with toolchains defaulting tohardfloat. Using such a compiler to build the kernel failsin the VFP directory witharch/arm/vfp/entry.S:1:0: sorry, unimplemented: -mfloat-abi=hard and VFPAdding -mfloat-abi=soft to the gcc command line fixes this.Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/arm/vfp/Makefile

222d394d - kbuild: enable 'make AFLAGS=...' to add additional options to AS

Mon, 15 Oct 2007 19:59:31 +0000

kbuild: enable 'make AFLAGS=...' to add additional options to ASThe variable AFLAGS is a wellknown variable and the usage bykbuild may result in unexpected behaviour.On top of that several people over time has asked for a way topass in additional flags to gcc.This patch replace use of AFLAGS with KBUILD_AFLAGS all overthe tree.Patch was tested on following architectures:alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390Signed-off-by: Sam Ravnborg List of files: /linux-6.15/arch/arm/vfp/Makefile

1a6be26d - [ARM] Enable VFP to be built when non-VFP capable CPUs are selected

Wed, 21 Jun 2006 12:51:41 +0000

[ARM] Enable VFP to be built when non-VFP capable CPUs are selectedSince we pass flags to the compiler to control code generation basedon the least capable selected CPU, if we want to include VFP support,we must tweak the assembler flags to allow the VFP instructions.Moreover, we must not use the mrrc/mcrr versions since these will notbe recognised by the assembler.We do not convert all instructions to the VFP-equivalent (yet) sincebinutils appears to barf on "fmrx rn, fpinst" and doesn't provide anyother way (other than using the mrc equivalent) to encode thisinstruction - which is rather a problem when you have a VFPimplementation which requires these instructions.Signed-off-by: Russell King List of files: /linux-6.15/arch/arm/vfp/Makefile

1da177e4 - Linux-2.6.12-rc2

Sat, 16 Apr 2005 22:20:36 +0000

Linux-2.6.12-rc2Initial git repository build. I'm not bothering with the full history,even though we have it. We can create a separate "historical" gitarchive of that later if we want to, and in the meantime it's about3.2GB when imported into git - space that would just make the earlygit days unnecessarily complicated, when we don't have a lot of goodinfrastructure for it.Let it rip!
