2017-11-01Add a fixed_size_mode classRichard Sandiford18-40/+131
This patch adds a fixed_size_mode machine_mode wrapper for modes that are known to have a fixed size. That applies to all current modes, but future patches will add support for variable-sized modes. The use of this class should be pretty restricted. One important use case is to hold the mode of static data, which can never be variable-sized with current file formats. Another is to hold the modes of registers involved in __builtin_apply and __builtin_result, since those interfaces don't cope well with variable-sized data. The class can also be useful when reinterpreting the contents of a fixed-length bit string as a different kind of value. 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (fixed_size_mode): New class. * rtl.h (get_pool_mode): Return fixed_size_mode. * gengtype.c (main): Add fixed_size_mode. * target.def (get_raw_result_mode): Return a fixed_size_mode.

2017-11-01Add a VEC_SERIES rtl codeRichard Sandiford10-25/+293
This patch adds an rtl representation of a vector linear series of the form: a[I] = BASE + I * STEP Like vec_duplicate; - the new rtx can be used for both constant and non-constant vectors - when used for constant vectors it is wrapped in a (const ...) - the constant form is only used for variable-length vectors; fixed-length vectors still use CONST_VECTOR At the moment the code is restricted to integer elements, to avoid concerns over floating-point rounding. 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi (vec_series): Document.

2017-11-01Allow vector CONSTsRichard Sandiford7-17/+63
This patch allows (const ...) wrappers to be used for rtx vector constants, as an alternative to const_vector. This is useful for SVE, where the number of elements isn't known until runtime. It could also be useful in future for fixed-length vectors, to reduce the amount of memory needed to represent simple constants with high element counts. However, one nice thing about keeping it restricted to variable-length vectors is that there is never any need to handle combinations of (const ...) and CONST_VECTOR. 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi (const): Update description of address constants.

2017-11-01Add more vec_duplicate simplificationsRichard Sandiford7-5/+264
This patch adds a vec_duplicate_p helper that tests for constant or non-constant vector duplicates. Together with the existing const_vec_duplicate_p, this complements the gen_vec_duplicate and gen_const_vec_duplicate added by a previous patch. The patch uses the new routines to add more rtx simplifications involving vector duplicates. These mirror simplifications that we already do for CONST_VECTOR broadcasts and are needed for variable-length SVE, which uses: (const:M (vec_duplicate:M X)) to represent constant broadcasts instead. The simplifications do trigger on the testsuite for variable duplicates too, and in each case I saw the change was an improvement. The best way of testing the new simplifications seemed to be via selftests. The patch cribs part of David's patch here: https://gcc.gnu.org/ml/gcc-patches/2016-07/msg00270.html . 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> David Malcolm <dmalcolm@redhat.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (vec_duplicate_p): New function. * selftest-rtl.c (assert_rtx_eq_at): New function. * selftest-rtl.h (ASSERT_RTX_EQ): New macro.

2017-11-01Add gen_(const_)vec_duplicate helpersRichard Sandiford17-217/+155
This patch adds helper functions for generating constant and non-constant vector duplicates. These routines help with SVE because it is then easier to use: (const:M (vec_duplicate:M X)) for a broadcast of X, even if the number of elements in M isn't known at compile time. It also makes it easier for general rtx code to treat constant and non-constant duplicates in the same way. In the target code, the patch uses gen_vec_duplicate instead of gen_rtx_VEC_DUPLICATE if handling constants correctly is potentially useful. It might be that some or all of the call sites only handle non-constants in practice, in which case the change is a harmless no-op (and a saving of a few characters). Otherwise, the target changes use gen_const_vec_duplicate instead of gen_rtx_CONST_VECTOR if the constant is obviously a duplicate. They also include some changes to use CONSTxx_RTX for easy global constants. 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * emit-rtl.h (gen_const_vec_duplicate): Declare.

2017-11-01Prevent invalid register mode changes in combineRichard Sandiford2-0/+13
This patch stops combine from changing the mode of an existing register in-place if doing so would change the size of the underlying register allocation size, as given by REGMODE_NATURAL_SIZE.

2017-10-31diagnostics: get rid of *_at_rich_loc in favor of overloadingDavid Malcolm30-250/+362
Adding a fix-it hint currently involves changing e.g.: error_at (token->location, "unknown type name %qE; did you mean %qs?", token->value, hint); to: gcc_rich_location richloc (token->location); richloc.add_fixit_replace (hint); error_at_rich_loc (&richloc, "unknown type name %qE; did you mean %qs?", token->value, hint); to make the change from taking a location_t to a rich_location *. This patch renames the "*_at_rich_loc" diagnostic entrypoints to use the same function names for rich_location * as for location_t, via overloading, to simplify the above change to just changing from: error_at (token->location, "unknown type name %qE; did you mean %qs?", token->value, hint); to: gcc_rich_location richloc (token->location); richloc.add_fixit_replace (hint); error_at (&richloc, "unknown type name %qE; did you mean %qs?", token->value, hint); thus saving space (and typing) and usually avoiding the need to reindent the "error_at" invocation. With this change, 0 is no longer acceptable as a location_t to these entrypoints, as e.g.: ../../src/gcc/auto-profile.c:855:37: error: call of overloaded 'inform(int, const char [18])' is ambiguous inform (0, "Not expected TAG."); ^ In file included from ../../src/gcc/auto-profile.c:35:0: ../../src/gcc/diagnostic-core.h:88:13: note: candidate: 'void inform(location_t, const char*, ...)' extern void inform (location_t, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3); ^~~~~~ ../../src/gcc/diagnostic-core.h:89:13: note: candidate: 'void inform(rich_location*, const char*, ...)' extern void inform (rich_location *, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3); ^~~~~~ Such locations now need to be spelled out as UNKNOWN_LOCATION, rather than 0. I considered making the API take a rich_location & rather than a rich_location *, but doing so would mean replacing diagnostic_set_info and diagnostic_set_info_translated with a constructor for diagnostic_info, which was a more invasive change.

If the user asks for a stack clash probe interval of 64kB, we currently generate a "stdu rX,-65536(r1)" instruction. That instruction does not exist (the offset is a 16-bit signed number). If the offset is too big we should force it into a register and generate a "stdux rX,rY,r1" instruction, instead.

2017-10-30Remove DImode expansions for 1-bit shiftsWilco Dijkstra4-67/+21
A left shift of 1 can always be done using an add, so slightly adjust rtx cost for DImode left shift by 1 so that adddi3 is preferred in all cases, and the arm_ashldi3_1bit is redundant. DImode right shifts of 1 are rarely used (6 in total in the GCC binary), so there is little benefit of the arm_ashrdi3_1bit and arm_lshrdi3_1bit patterns. The generated code is better and faster without these shifts as it allows early expansion, optimization and better register allocation. gcc/ * config/arm/arm.md (ashldi3): Remove shift by 1 expansion. (arm_ashldi3_1bit): Remove pattern. (ashrdi3): Remove shift by 1 expansion. (arm_ashrdi3_1bit): Remove pattern. (lshrdi3): Remove shift by 1 expansion.
