sh: also try passing -m4-nofpu for SH2A builds

2014-07-23T22:10:54+00:00

When compiling a SH2A kernel (e.g.  se7206_defconfig or rsk7203_defconfig)
using sh4-linux-gcc, linking fails with:

  net/built-in.o: In function `__sk_run_filter':
  net/core/filter.c:566: undefined reference to `__fpscr_values'
  net/core/filter.c:269: undefined reference to `__fpscr_values'
  ...
  net/built-in.o:net/core/filter.c:580: more undefined references to `__fpscr_values' follow

This happens because sh4-linux-gcc doesn't support the "-m2a-nofpu",
which is thus filtered out by "$(call cc-option, ...)".

As compiling using sh4-linux-gcc is useful for compile coverage, also
try passing "-m4-nofpu" (which is presumably filtered out when using a
real sh2a-linux toolchain) to disable the generation of FPU instructions
and references to __fpscr_values[].

stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between architectures

2013-12-20T08:38:40+00:00

Instead of duplicating the CC_STACKPROTECTOR Kconfig and
Makefile logic in each architecture, switch to using
HAVE_CC_STACKPROTECTOR and keep everything in one place. This
retains the x86-specific bug verification scripts.

sh: Setup CROSS_COMPILE at the top

2012-06-13T02:42:13+00:00

CROSS_COMPILE must be setup before using e.g. cc-option (and a few other
as-*, cc-*, ld-* macros), else they will check against the wrong compiler
when cross-compiling, and may invoke the cross compiler with wrong or
suboptimal compiler options.

sh-linux-gnu-ld:--defsym 'jiffies=jiffies_64': ignoring invalid character `'' in expression

For some reason ld has recently started complaining about the quotes, so just
get rid of them, we don't need them for anything anyways.

sh: Use generic init_task

2012-05-05T11:00:25+00:00

Same code. Use the generic version. The special Makefile treatment is
pointless anyway as init_task.o contains only data which is handled by
the linker script. So no point on being treated like head text.

sh: initial stack protector support.

2012-04-19T06:45:57+00:00

This implements basic -fstack-protector support, based on the early ARM
version in c743f38013aeff58ef6252601e397b5ba281c633. The SMP case is
limited to the initial canary value, while the UP case handles per-task
granularity (limited to 32-bit sh until a new enough sh64 compiler
manifests itself).

serial: sh-sci: Abstract register maps.

2011-06-14T03:40:19+00:00

This takes a bit of a sledgehammer to the horribly CPU subtype
ifdef-ridden header and abstracts all of the different register layouts
in to distinct types which in turn can be overriden on a per-port basis,
or permitted to default to the map matching the port type at probe time.

In the process this ultimately fixes up inumerable bugs with mismatches
on various CPU types (particularly the legacy ones that were obviously
broken years ago and no one noticed) and provides a more tightly coupled
and consolidated platform for extending and implementing generic
features.
