I tried using 'svn merge' to do the merge but it did a terrible job and there were bazillions of conflicts. So instead I just took the diff between the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed the added files (no files needed to be 'svn remove'd) and committed. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10156

/* Details about the capabilities of the underlying (host) CPU. These
|
|
details are acquired by (1) enquiring with the CPU at startup, or
|
|
(2) from the AT_SYSINFO entries the kernel gave us (ppc cache
|
|
line size). It's a bit nasty in the sense that there's no obvious
|
|
way to stop uses of some of this info before it's ready to go.
|
|
|
|
Current dependencies are:
|
|
|
|
x86: initially: call VG_(machine_get_hwcaps)
|
|
|
|
then safe to use VG_(machine_get_VexArchInfo)
|
|
and VG_(machine_x86_have_mxcsr)
|
|

|
|
amd64: initially: call VG_(machine_get_hwcaps)
|
|
|
|
then safe to use VG_(machine_get_VexArchInfo)
|
|
-------------
|
|
ppc32: initially: call VG_(machine_get_hwcaps)
|
|
call VG_(machine_ppc32_set_clszB)
|
|
|
|
then safe to use VG_(machine_get_VexArchInfo)
|
|
and VG_(machine_ppc32_has_FP)

and VG_(machine_ppc32_has_VMX)

|
then safe to use VG_(machine_get_VexArchInfo)
|

and VG_(machine_ppc64_has_VMX)
|
|
|
|
VG_(machine_get_hwcaps) may use signals (although it attempts to
|
|
leave signal state unchanged) and therefore should only be
|
|
called before m_main sets up the client's signal state.
