2018-01-12rs6000: Remove -mstringSegher Boessenkool10-775/+72
-mstring is only enabled by default on 601, and with -Os on some configurations. It is almost always slower (than not using it) and does not very often lead to smaller code. This patch disables it. If a user uses -mstring he gets a warning (but not with -mno-string). I left the target attribute in place, it just doesn't do anything anymore. The patch also deletes a whole bunch of code.

2018-01-12Handle polynomial DR_INITRichard Sandiford3-5/+21
The idea with the main 107-patch poly_int series (latterly 109-patch) was to change the mode sizes and vector element counts to poly_int and then propagate those changes as far as they needed to go to fix build failures from incompatible types. This means that DR_INIT is now constructed as a poly_int64: poly_int64 pbytepos; if (!multiple_p (pbitpos, BITS_PER_UNIT, &pbytepos)) { if (dump_file && (dump_flags & TDF_DETAILS)) fprintf (dump_file, "failed: bit offset alignment.\n"); return false; } [...] init = ssize_int (pbytepos); This patch adjusts other references to DR_INIT accordingly. Unlike the above, the adjustments weren't needed to avoid a build-time type incompatibility, but they are needed to make the producer and consumers of DR_INIT logically consistent. 2018-01-12 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-predcom.c (aff_combination_dr_offset): Use wi::to_poly_widest rather than wi::to_widest for DR_INITs. * tree-vect-data-refs.c (vect_find_same_alignment_drs): Use wi::to_poly_offset rather than wi::to_offset for DR_INIT.

2018-01-12Handle poly_int vector sizes in get_vec_alignment_for_array_typeRichard Sandiford2-3/+9
get_vectype_for_scalar_type returns a variable-length vector type for SVE, whereas get_vec_alignment_for_array_type assumed it would always be an INTEGER_CST. This is needed to build libstdc++-v3/src/closures.cc for SVE (and probably many other places besides -- this was just the first hit). 2018-01-12 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-vectorizer.c (get_vec_alignment_for_array_type): Handle polynomial type sizes.

2018-01-12Allow variable-sized temporary variables in gimplify.cRichard Sandiford2-2/+8
This is needed to build libgfortran for SVE. The OpenMP code needs to create temporary vector variables, and the variables will therefore be variable-sized for SVE. Earlier patches made such variables work. 2018-01-12 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * gimplify.c (gimple_add_tmp_var_fn): Allow variables to have a poly_uint64 size, rather than requiring an unsigned HOST_WIDE_INT size.

2018-01-11i386: Align stack frame if argument is passed on stackH.J. Lu4-1/+46
When a function call is removed, it may become a leaf function. But if argument may be passed on stack, we need to align the stack frame when there is no tail call. Tested on Linux/i686 and Linux/x86-64. gcc/ PR target/83330 * config/i386/i386.c (ix86_compute_frame_layout): Align stack frame if argument is passed on stack. gcc/testsuite/ PR target/83330 * gcc.target/i386/pr83330.c: New test.
