[arm] Fix incorrect __ARM_ARCH_PROFILE for -march=armv7

ACLE explicitly states that when targetting the common subset of
ARMv7-A, ARMv7-R and ARMv7-M, the __ARM_ARCH_PROFILE macro should not
be set.  We currently set it to 'M' which is clearly erroneous.

The logic for creating this is very convoluted and also somewhat
fragile, so I've taken the opportunity to use the new CPU and
architecture definition infrastructure to record the profile for each
architecture explicitly rather than try to reconstruct it from other
data.  I think this results in a much more robust solution.

7 years agoFix genmultilib reuse rule checks for large sets of option combinations.
Joseph Myers [Tue, 27 Jun 2017 17:33:28 +0000 (18:33 +0100)]
Fix genmultilib reuse rule checks for large sets of option combinations.

genmultilib computes combination_space, a list of all combinations of
options in MULTILIB_OPTIONS that might have multilibs built for them
(some of which may end up not having multilibs built for them, and
some of those may end up being mapped to other multilibs with
MULTILIB_REUSE).  It is then used to validate the right hand part of
MULTILIB_REUSE rules, checking with expr that combination_space
matches a basic regular expression derived from that right hand part.

There are two problems with this approach to validation:

* It requires that right hand part to have options in the same order
  as in MULTILIB_OPTIONS, in contradiction to the documentation of
  MULTILIB_REUSE saying that order does not matter there.

* combination_space can be so large that the expr call fails with an
  E2BIG error.  I have a local ARM configuration with 40 multilibs but
  3840 combinations of options from MULTILIB_OPTIONS (so 3839 listed
  in combination_space, since it doesn't list the default multilib)
  and 996 MULTILIB_REUSE rules.  This generates a combination_space
  string longer than the Linux kernel's MAX_ARG_STRLEN (PAGE_SIZE *
  32, the limit on the length of a single argv string), so that expr
  cannot be run.

This patch changes the validation approach to generate a much shorter
extended regular expression for any sequence of multilib options in
any order, and uses that for the validation instead.

Tested with a build for arm-none-eabi --with-multilib-list=aprofile
(as a configuration that uses MULTILIB_REUSE).

* genmultilib (combination_space): Remove variable.
Validate reuse rules against regular expression for any sequence
of multilib options in any order.

7 years agoruntime: complete defer handling in CgocallBackDone
Ian Lance Taylor [Fri, 23 Jun 2017 20:19:40 +0000 (20:19 +0000)]
runtime: complete defer handling in CgocallBackDone

    When C code calls a Go function, it actually calls a function
    generated by cgo. That function is written in Go, and, among other
    things, it calls the real Go function like this:
            CgocallBack()
            defer CgocallBackDone()
            RealGoFunction()
    The deferred CgocallBackDone function enters syscall mode as we return
    to C. Typically the C function will then eventually return to Go.

    However, in the case where the C function is running on a thread
    created in C, it will not return to Go. For that case we will have
    allocated an m struct, with an associated g struct, for the duration
    of the Go code, and when the Go is complete we will return the m and g
    to a free list.

    That all works, but we are running in a deferred function, which means
    that we have been invoked by deferreturn, and deferreturn expects to
    do a bit of cleanup to record that the defer has been completed. Doing
    that cleanup while using an m and g that have already been returned to
    the free list is clearly a bad idea. It was kind of working because
    deferreturn was holding the g pointer in a local variable, but there
    were races with some other thread picking up and using the newly freed g.
    It was also kind of working because of a special check in freedefer;
    that check is no longer necessary.

    This patch changes the special case of releasing the m and g to do the
    defer cleanup in CgocallBackDone itself.

    This patch also checks for the special case of a panic through
    CgocallBackDone. In that special case, we don't want to release the m
    and g. Since we are returning to C code that was not called by Go
    code, we know that the panic is not going to be caught and we are
    going to exit the program. So for that special case we keep the m and
    g structs so that the rest of the panic code can use them.
