The build servers have GNU coreutils 5.93, where stat does not output
a newline. Ubuntu hardy has GNU coreutils 6.10, where it does.
Lacking a newline messes up the summing of the sizes. Fix
get-file-size to remove the newline if present, and make the total
calculation in assert-max-file-size more robust.
Also, if the image was too big, it was not actually making the build
fail (because /bin/false was not the last thing called). Fix that so
it does.
This allows TARGET_ARCH_VARIANT to be set by the vendor before we choose the
architecture in core/combo/select.mk.
Also add a primitive armv7-a.mk for turning on hardware floating point.
This is currently a copy & paste of the armv5te parameters. I don't
know if there's a better way to encode this, or to what extent we will
need to specialize it vs. armv5te in a future build (e.g. to enable fp
instruction use in code gen).
Currently the only effect is to select the VFP-enabled mterp sources in
Dalvik.
armv4 was only implemented on StrongArm and Arm8 (See http://en.wikipedia.org/wiki/ARM_architecture)
and will be more difficult to support since it does not support the bx instruction.
armv4t on the other hand is used in a wide range of cpu:s.
armv4 is also not supported by bionic or dalvik, but armv4t is.
Thumb-mode is not yet enabled since there are some unresolved abi-issues.
architecture versions other than ARMv5TE.
The general approach is to provide TARGET_ARCH_VERSION, to complement
TARGET_ARCH. This defaults to the current armv5te. The variable
values should match the architectures as defined by gcc.
There is a block of defines for each supported architecture version
(currently ARMv5TE and ARMv4). Each block defines a set of features
using ARCH_ARM_HAVE_<x> variables. It also specifies a set of c
preprocessor defines to pass to the compiler. Finally it defines a
default CPU. (As for architecture versions, the default CPU should
match a CPU that gcc knows about.)
Support is added for architectures that do not support THUMB. Specifically
we change the 'thumb compile' target to simply compile as ARM code
instead, and we change the interworking flag passed to the compiler.
Finally, we ensure that the system/core/include/arch/linux-arm directory
is added to the default include path, which allows the use of asm/macros.h
header file described in review #1626. The way in which this done is
considerably unclean/hacky, if someone can suggest a better way please
let me know.
