[gcc]
2014-11-17  Michael Meissner  <meissner@linux.vnet.ibm.com>
    Ulrich Weigand  <Ulrich.Weigand@de.ibm.com>

* config/rs6000/rs6000.c (RELOAD_REG_AND_M16): Add support for
Altivec style vector loads that ignore the bottom 3 bits of the
address.
(rs6000_debug_addr_mask): New function to print the addr_mask
values if debugging.
(rs6000_debug_print_mode): Call rs6000_debug_addr_mask to print
out addr_mask.
(rs6000_setup_reg_addr_masks): Add support for Altivec style
vector loads that ignore the bottom 3 bits of the address.  Allow
pre-increment and pre-decrement on floating point, even if the
-mupper-regs-{sf,df} options were used.
(rs6000_init_hard_regno_mode_ok): Rework DFmode support if
-mupper-regs-df.  Add support for -mupper-regs-sf.  Rearrange code
placement for direct move support.
(rs6000_option_override_internal): Add checks for -mupper-regs-df
requiring -mvsx, and -mupper-regs-sf requiring -mpower8-vector.
If -mupper-regs, set both -mupper-regs-sf and -mupper-regs-df,
depending on the underlying cpu.
(rs6000_secondary_reload_fail): Add ATTRIBUTE_NORETURN.
(rs6000_secondary_reload_toc_costs): Helper function to identify
costs of a TOC load for secondary reload support.
(rs6000_secondary_reload_memory): Helper function for secondary
reload, to determine if a particular memory operation is directly
handled by the hardware, or if it needs support from secondary
reload to create a valid address.
(rs6000_secondary_reload): Rework code, to be clearer.  If the
appropriate -mupper-regs-{sf,df} is used, use FPR registers to
reload scalar values, since the FPR registers have D-form
addressing. Move most of the code handling memory to the function
rs6000_secondary_reload_memory, and use the reg_addr structure to
determine what type of address modes are supported.  Print more
debug information if -mdebug=addr.
(rs6000_secondary_reload_inner): Rework entire function to be more
general.  Use the reg_addr bits to determine what type of
addressing is supported.
(rs6000_preferred_reload_class): Rework.  Move constant handling
into a single place.  Prefer using FLOAT_REGS for scalar floating
point.
(rs6000_secondary_reload_class): Use a FPR register to move a
value from an Altivec register to a GPR, and vice versa.  Move VSX
handling above traditional floating point.

* config/rs6000/rs6000.md (mov<mode>_hardfloat, FMOVE32 case):
Delete some spaces in the constraints.
(DF->DF move peephole2): Disable if -mupper-regs-{sf,df} to
allow using FPR registers to load/store an Altivec register for
scalar floating point types.
(SF->SF move peephole2): Likewise.
(DFmode splitter): Add a define_split to move floating point
constants to the constant pool before register allocation.
Normally constants are put into the pool immediately, but
-ffast-math delays putting them into the constant pool for the
reciprocal approximation support.
(SFmode splitter): Likewise.

* config/rs6000/rs6000.opt (-mupper-regs-df): Make option public.

__UPPER_REGS_DF__ if -mupper-regs-df.  Define __UPPER_REGS_SF__ if
-mupper-regs-sf.
(-mupper-regs): New combination option that sets -mupper-regs-sf
and -mupper-regs-df by default if the cpu supports the instructions.

* doc/invoke.texi (RS/6000 and PowerPC Options): Document
-mupper-regs, -mupper-regs-sf, and -mupper-regs-df.

* config/rs6000/predicates.md (memory_fp_constant): New predicate
to return true if the operand is a floating point constant that
must be put into the constant pool, before register allocation
occurs.

* config/rs6000/rs6000-cpus.def (ISA_2_6_MASKS_SERVER): Enable
-mupper-regs-df by default.
(ISA_2_7_MASKS_SERVER): Enable -mupper-regs-sf by default.
(POWERPC_MASKS): Add -mupper-regs-{sf,df} as options set by the
various -mcpu=... options.
(power7 cpu): Enable -mupper-regs-df by default.

* doc/invoke.texi (RS/6000 and PowerPC Options): Document
