2016-11-18Use rtx_mode_t instead of std::make_pairRichard Sandiford1-1/+1
This change makes the code less sensitive to the exact type of the mode, i.e. it forces a conversion where necessary. This becomes important when wrappers like scalar_int_mode and scalar_mode can also be used instead of machine_mode. Using rtx_mode_t also abstracts away the representation. The fact that it's a std::pair rather than a custom class isn't important to users of the interface. gcc/ 2016-11-18 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * combine.c (try_combine): Use rtx_mode_t instead of std::make_pair. * dwarf2out.c (mem_loc_descriptor, loc_descriptor): Likewise.

2016-11-16Optimise CONCAT handling in emit_group_loadRichard Sandiford1-6/+9
The CONCAT handling in emit_group_load chooses between doing an extraction from a single component or forcing the whole thing to memory and extracting from there. The condition for the former (more efficient) option was: if ((bytepos == 0 && bytelen == slen0) || (bytepos != 0 && bytepos + bytelen <= slen)) On the one hand this seems dangerous, since the second line allows bit ranges that start in the first component and leak into the second. On the other hand it seems strange to allow references that start after the first byte of the second component but not those that start after the first byte of the first component. This led to a pessimisation of things like gcc.dg/builtins-54.c for hppa64-hp-hpux11.23. This patch simply checks whether the reference is contained within a single component. It also makes sure that we do an extraction on anything that doesn't span the whole component (even if it's constant). gcc/ 2016-11-15 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * expr.c (emit_group_load_1): Tighten check for whether an access involves only one operand of a CONCAT. Use extract_bit_field for constants if the bit range does span the whole operand.

2016-05-02Add a wi::to_wide helper functionRichard Sandiford1-3/+2
As Richard says, we ought to have a convenient way of converting an INTEGER_CST to a wide_int of a particular precision without having to extract the sign of the INTEGER_CST's type each time. This patch adds a wi::to_wide helper for that, alongside the existing wi::to_offset and wi::to_widest. Tested on x86_64-linux-gnu and aarch64-linux-gnu. gcc/ * tree.h (wi::to_wide): New function. * expr.c (expand_expr_real_1): Use wi::to_wide. * fold-const.c (int_const_binop_1): Likewise.

2016-05-02Support << and >> for offset_int and widest_intRichard Sandiford1-3/+3
Following on from the comparison patch, I think it makes sense to support << and >> for offset_int (int128_t) and widest_int (intNNN_t), with >> being arithmetic shift. It doesn't make sense to use logical right shift on a potentially negative offset_int, since the precision of 128 bits has no meaning on the target. Tested on x86_64-linux-gnu and aarch64-linux-gnu. gcc/ * wide-int.h: Update offset_int and widest_int documentation. (WI_SIGNED_SHIFT_RESULT): New macro. (wi::binary_shift): Define signed_shift_result_type for shifts on offset_int- and widest_int-like types.
