2017-10-23Convert STARTING_FRAME_OFFSET to a hookRichard Sandiford1-1/+2
I took the documentation of the FRAME_GROWS_DOWNWARD behaviour from the version that was in most header files, since the one in the manual seemed less clear. The patch deliberately keeps FIRST_PARM_OFFSET(FNDECL) in microblaze_starting_frame_offset; this seems to be a port-local convention and takes advantage of the fact that FIRST_PARM_OFFSET doesn't read FNDECL. 2017-10-23 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (starting_frame_offset): New hook. * doc/tm.texi (STARTING_FRAME_OFFSET): Remove in favor of...

2017-09-25Turn CONSTANT_ALIGNMENT into a hookRichard Sandiford1-1/+1
The definition: #define CONSTANT_ALIGNMENT(EXP, ALIGN) \ (TREE_CODE (EXP) == STRING_CST \ && (ALIGN) < BITS_PER_WORD ? BITS_PER_WORD : (ALIGN)) was very common, so the patch adds a canned definition for that, called constant_alignment_word_strings. Some ports had a variation that used a port-local FASTEST_ALIGNMENT instead of BITS_PER_WORD; the patch uses constant_alignment_word_strings if FASTEST_ALIGNMENT was always BITS_PER_WORD and a port-local hook function otherwise. 2017-09-25 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (constant_alignment): New hook. * defaults.h (CONSTANT_ALIGNMENT): Delete. * doc/tm.texi.in (CONSTANT_ALIGNMENT): Replace with...

2017-09-13Turn SECONDARY_MEMORY_NEEDED_MODE into a target hookRichard Sandiford1-1/+1
This includes a change to LRA. Previously the code was: if (sclass == NO_REGS && dclass == NO_REGS) return false; #ifdef SECONDARY_MEMORY_NEEDED if (SECONDARY_MEMORY_NEEDED (sclass, dclass, GET_MODE (src)) #ifdef SECONDARY_MEMORY_NEEDED_MODE && ((sclass != NO_REGS && dclass != NO_REGS) || GET_MODE (src) != SECONDARY_MEMORY_NEEDED_MODE (GET_MODE (src))) #endif ) { *sec_mem_p = true; return false; } #endif in which the positioning of the second ifdef meant that defining SECONDARY_MEMORY_NEEDED_MODE to its default value was not a no-op: without a definition, we would consider using secondary reloads for mem<-reg and reg<-mem reloads even if the secondary memory has the same mode as the original mem, while defining it would avoid this. The latter behaviour seems correct. The default is different for reload and LRA. For LRA the default is to use the original mode, while reload promotes smaller-than-word integral modes to word mode: if (GET_MODE_BITSIZE (mode) < BITS_PER_WORD && INTEGRAL_MODE_P (mode)) mode = mode_for_size (BITS_PER_WORD, GET_MODE_CLASS (mode), 0).require (); Some of the ports that have switched to LRA seemed to have SECONDARY_MEMORY_NEEDED_MDOEs based on the old reload definition, and still referred to the reload.c:get_secondary_mem function in the comments. The patch just keeps them as-is. 2017-09-13 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * target.def (secondary_memory_needed_mode): New hook: * targhooks.c (default_secondary_memory_needed_mode): Declare. * targhooks.h (default_secondary_memory_needed_mode): New function. * doc/tm.texi.in (SECONDARY_MEMORY_NEEDED_MODE): Replace with...

2017-09-04Turn HARD_REGNO_CALL_PART_CLOBBERED into a target hookRichard Sandiford1-1/+2
The SVE patches change the size of a machine_mode from a compile-time constant to a runtime invariant. However, target-specific code can continue to treat the modes as constant-sized if the target only has constant-sized modes. The main snag with this approach is that target-independent code still uses macros from the target .h file. This patch is one of several that converts a target macro to a hook. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * target.def (hard_regno_call_part_clobbered): New hook. * doc/tm.texi.in (HARD_REGNO_CALL_PART_CLOBBERED): Replace with...

2017-08-30[3/77] Allow machine modes to be classesRichard Sandiford1-0/+6
This patch makes various changes that allow modes like SImode to be classes rather than enums. Firstly, it adds inline functions for all mode size properties, with the macros being simple wrappers around them. This is necessary for the __builtin_constant_p trick to continue working effectively when the mode arguments are slightly more complex (but still foldable at compile time). These inline functions are trivial and heavily used. There's not much point keeping them out-of-line at -O0: if anything it would make debugging harder rather than easier, and it would also slow things down. The patch therefore marks them as "always_inline", if that's available. Later patches use this approach too. Using inline functions means that it's no longer possible to pass an int to GET_MODE_PRECISION etc. The Fortran and powerpcspe-c.c parts are needed to avoid instances of that. The patch continues to use enums for gencondmd.c, so that more mode comparisons are integer constant expressions when checking for always-true or always-false conditions. This is the only intended use of USE_ENUM_MODES. The patch also enforces the previous replacement of case statements by defining modes as: #define FOOmode ((void) 0, E_FOOmode) This adds no overhead but makes sure that new uses of "case FOOmode:" don't accidentally creep in when FOOmode has no specific class associated with it. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * genconditions.c (write_header): Add a "#define USE_ENUM_MODES". * genmodes.c (emit_insn_modes_h): Define FOOmode to E_FOOmode if USE_ENUM_MODES is defined and to ((void) 0, E_FOOmode) otherwise. * machmode.h (mode_size): Move earlier in file.

2015-06-04Remove TARGET_RELAXED_ORDERING and optimize for weak memory models.Ramana Radhakrishnan1-1/+1
This patch removes the special casing for targets with relaxed memory ordering and handles guard accesses with equivalent atomic load acquire operations. In this process we change the algorithm to load the guard variable with an atomic load that has ACQUIRE semantics. This then means that on targets which have weak memory models, the fast path is inlined and can directly use a load-acquire instruction where available (and yay! one more hook gone). 2015-06-04 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com> PR c++/66192 PR target/66200 * doc/tm.texi: Regenerate. * doc/tm.texi.in (TARGET_RELAXED_ORDERING): Delete. * target.def (TARGET_RELAXED_ORDERING): Likewise. * config/alpha/alpha.c (TARGET_RELAXED_ORDERING): Likewise. * config/ia64/ia64.c (TARGET_RELAXED_ORDERING): Likewise. * config/rs6000/rs6000.c (TARGET_RELAXED_ORDERING): Likewise. * config/sparc/linux.h (SPARC_RELAXED_ORDERING): Likewise. * config/sparc/linux64.h (SPARC_RELAXED_ORDERING): Likewise. * config/sparc/sparc.c (TARGET_RELAXED_ORDERING): Likewise. * config/sparc/sparc.h (SPARC_RELAXED_ORDERING): Likewise. * system.h (TARGET_RELAXED_ORDERING): Poison. 2015-06-04 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com> PR c++/66192 PR target/66200 * cp-tree.h (get_guard_cond): Adjust declaration * decl.c (expand_static_init): Use atomic load acquire and adjust call to get_guard_cond. * decl2.c (build_atomic_load_byte): New function.
