2017-12-20poly_int: get_ref_base_and_extentRichard Sandiford1-8/+6
This patch changes the types of the bit offsets and sizes returned by get_ref_base_and_extent to poly_int64. There are some callers that can't sensibly operate on polynomial offsets or handle cases where the offset and size aren't known exactly. This includes the IPA devirtualisation code (since there's no defined way of having vtables at variable offsets) and some parts of the DWARF code. The patch therefore adds a helper function get_ref_base_and_extent_hwi that either returns exact HOST_WIDE_INT bit positions and sizes or returns a null base to indicate failure. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-dfa.h (get_ref_base_and_extent): Return the base, size and max_size as poly_int64_pods rather than HOST_WIDE_INTs.

2017-12-20poly_int: DWARF CFA offsetsRichard Sandiford1-0/+3
This patch makes the DWARF code use poly_int64 rather than HOST_WIDE_INT for CFA offsets. The main changes are: - to make reg_save use a DW_CFA_expression representation when the offset isn't constant and - to record the CFA information alongside a def_cfa_expression if either offset is polynomial, since it's quite difficult to reconstruct the CFA information otherwise. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * gengtype.c (main): Handle poly_int64_pod. * dwarf2out.h (dw_cfi_oprnd_cfa_loc): New dw_cfi_oprnd_type.

2017-12-20poly_int: SUBREG_BYTERichard Sandiford1-3/+3
This patch changes SUBREG_BYTE from an int to a poly_int. Since valid SUBREG_BYTEs must be contained within the mode of the SUBREG_REG, the required range is the same as for GET_MODE_SIZE, i.e. unsigned short. The patch therefore uses poly_uint16(_pod) for the SUBREG_BYTE. Using poly_uint16_pod rtx fields requires a new field code ('p'). Since there are no other uses of 'p' besides SUBREG_BYTE, the patch doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE instead. The patch doesn't bother implementing 'p' support for legacy define_peepholes, since none of the remaining ones have subregs in their patterns. As it happened, the rtl documentation used SUBREG as an example of a code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1). Since there's no direct replacement for XINT, and since people should never use it even if there were, the patch changes the example to use INT_LIST instead. The patch also changes subreg-related helper functions so that they too take and return polynomial offsets. This makes the patch quite big, but it's mostly mechanical. The patch generally sticks to existing choices wrt signedness. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi: Update documentation of SUBREG_BYTE.

2017-12-20poly_int: MEM_OFFSET and MEM_SIZERichard Sandiford1-3/+5
This patch changes the MEM_OFFSET and MEM_SIZE memory attributes from HOST_WIDE_INT to poly_int64. Most of it is mechanical, but there is one nonbovious change in widen_memory_access. Previously the main while loop broke with: /* Similarly for the decl. */ else if (DECL_P (attrs.expr) && DECL_SIZE_UNIT (attrs.expr) && TREE_CODE (DECL_SIZE_UNIT (attrs.expr)) == INTEGER_CST && compare_tree_int (DECL_SIZE_UNIT (attrs.expr), size) >= 0 && (! attrs.offset_known_p || attrs.offset >= 0)) break; but it seemed wrong to optimistically assume the best case when the offset isn't known (and thus might be negative). As it happens, the "! attrs.offset_known_p" condition was always false, because we'd already nullified attrs.expr in that case: /* If we don't know what offset we were at within the expression, then we can't know if we've overstepped the bounds. */ if (! attrs.offset_known_p) attrs.expr = NULL_TREE; The patch therefore drops "! attrs.offset_known_p ||" when converting the offset check to the may/must interface. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (mem_attrs): Add a default constructor.

2017-12-20poly_int: DWARF locationsRichard Sandiford1-49/+111
This patch adds support for DWARF location expressions that involve polynomial offsets. It adds a target hook that says how the runtime invariants used in the offsets should be represented in DWARF. SVE vectors have to be a multiple of 128 bits in size, so the GCC port uses the number of 128-bit blocks minus one as the runtime invariant. However, in DWARF, the vector length is exposed via a pseudo "VG" register that holds the number of 64-bit elements in a vector. Thus: indeterminate 1 == (VG / 2) - 1 The hook needs to be general enough to express this. Note that in most cases the division and subtraction fold away into surrounding expressions. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * target.def (dwarf_poly_indeterminate_value): New hook. * targhooks.h (default_dwarf_poly_indeterminate_value): Declare. * targhooks.c (default_dwarf_poly_indeterminate_value): New function. * doc/tm.texi.in (TARGET_DWARF_POLY_INDETERMINATE_VALUE): Document. * doc/tm.texi: Regenerate. * dwarf2out.h (build_cfa_loc, build_cfa_aligned_loc): Take the offset as a poly_int64. * dwarf2out.c (new_reg_loc_descr): Move later in file.

2017-12-20poly_int: rtx constantsRichard Sandiford1-0/+10
This patch adds an rtl representation of poly_int values. There were three possible ways of doing this: (1) Add a new rtl code for the poly_ints themselves and store the coefficients as trailing wide_ints. This would give constants like: (const_poly_int [c0 c1 ... cn]) The runtime value would be: c0 + c1 * x1 + ... + cn * xn (2) Like (1), but use rtxes for the coefficients. This would give constants like: (const_poly_int [(const_int c0) (const_int c1) ... (const_int cn)]) although the coefficients could be const_wide_ints instead of const_ints where appropriate. (3) Add a new rtl code for the polynomial indeterminates, then use them in const wrappers. A constant like c0 + c1 * x1 would then look like: (const:M (plus:M (mult:M (const_param:M x1) (const_int c1)) (const_int c0))) There didn't seem to be that much to choose between them. The main advantage of (1) is that it's a more efficient representation and that we can refer to the cofficients directly as wide_int_storage. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi (const_poly_int): Document.

This patch adjusts numerous parts of the compiler that would malfunction should they find debug markers at points where they may be introduced. The changes purport to allow the compiler to pass bootstrap-debug-lean (-fcompare-debug in stage3) at various optimization levels, as well as bootstrap-debug-lib (-fcompare-debug for target libraries), even after the compiler is changed so that debug markers are introduced in code streams at spots where earlier debug stmts, insns and notes wouldn't normally appear.

2017-11-23Fix .debug_rnglists generation with -gdwarf-5 -gsplit-dwarf.Mark Wielaard1-9/+18
Early debug broke generation of .debug_rnglists when using both -gdwarf5 and -gsplit-dwarf. It introduces a generation for init_sections_and_labels, but doesn't account for the generation of up to 4 unique ranges labels, two created in init_sections_and_labels and two in output_rnglists. Fix this by passing generation to output_rnglists and creating 4 unique labels per generation.

2017-11-15Use compare-debug for bootstrap-debug-lean to ignore != DW_AT_producerAlexandre Oliva1-0/+1
Unlike bootstrap-debug, bootstrap-debug-lean used to pass compare using the traditional compare command, because it compiled both stage2 and stage3 with options that used to generate identical output (-fcompare-debug= in stage2 vs -fcompare-debug in stage3). Since we started adding relevant command-line flags to DW_AT_producer, this is no longer the case, and stages 2 and 3 object files that differ in nothing but the DW_AT_producer strings. -fcompare-debug is short for -fcompare-debug=-gtoggle, so stage3 compiles twice, once with the normal options, once with toggled -g, to then compare the temporary final dumps. When enabled, both compilations get from the driver an additional -frandom-seed flag (if none is given explicitly). -fcompare-debug= is short for -fno-compare-debug, disabling the second compilation. The difference between the DW_AT_producer lines are the different -fcompare-debug flags, and the presence of the -frandom-seed flag in the stage3 compilation. It is easy and sensible enough to filter the -fcompare-debug flags out of the DW_AT_producer string. This option should never affect the compilation output, it just determines whether or not to perform an additional compilation that should produce the same executable output. However, dropping -frandom-seed is not quite correct, in that it might have other consequences on the compilation. So, it makes little sense to make the effort to drop it when it's implicit; for those comparing compiler output differences, it might even hint at what causes, and could fix, difficult to explain differences, namely, explicitly supplying -frandom-seed options. They don't seem to matter for compiler bootstraps, though, at least for now, so we can safely refrain from issuing -frandom-seed (or maybe we already issue it where needed :-), and then, for bootstrap-debug-lean, use the compare-debug script, that strips out debug information before comparing the object files. for config/ChangeLog * bootstrap-debug-lean.mk (do-compare): Use the contrib/compare-debug script. for gcc/ChangeLog * dwarf2out.c (gen_producer_string): Discard OPT_fcompare_debug.

2017-11-07FT32 makes use of multiple address spaces.James Bowman1-2/+3
FT32 makes use of multiple address spaces. When trying to inspect objects in GDB, GDB was treating them as a straight "const". The cause seems to be in GCC DWARF2 output. This output is handled in gcc/gcc/dwarf2out.c, where modified_type_die() checks that TYPE has qualifiers CV_QUALS. However while TYPE has ADDR_SPACE qualifiers, the modified_type_die() explicitly discards the ADDR_SPACE qualifiers. This patch retains the ADDR_SPACE qualifiers as modified_type_die() outputs the DWARF type tree. This allows the types to match, and correct type information for the object is emitted.

2017-10-30Add -std=c17, -std=gnu17.Joseph Myers1-1/+4
C17, a bug-fix version of the C11 standard with DR resolutions integrated, will soon go to ballot. This patch adds corresponding options -std=c17, -std=gnu17 (new default version, replacing -std=gnu11 as the default), -std=iso9899:2017. As a bug-fix version of the standard, there is no need for flag_isoc17 or any options for compatibility warnings; however, there is a new __STDC_VERSION__ value, so new cpplib languages CLK_GNUC17 and CLK_STDC17 are added to support using that new value with the new options. (If the standard ends up being published in 2018 and being known as C18, option aliases can be added. Note however that -std=iso9899:199409 corresponds to a __STDC_VERSION__ value rather than a publication date.) (There are a couple of DR resolutions needing implementing in GCC, but that's independent of the new options.) (I'd propose to add -std=c2x / -std=gnu2x / -Wc11-c2x-compat for the next major C standard revision once there are actually C2x drafts being issued with new features included.)

2017-10-10Require wi::to_wide for treesRichard Sandiford1-2/+2
The wide_int routines allow things like: wi::add (t, 1) to add 1 to an INTEGER_CST T in its native precision. But we also have: wi::to_offset (t) // Treat T as an offset_int wi::to_widest (t) // Treat T as a widest_int Recently we also gained: wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC This patch therefore requires: wi::to_wide (t) when operating on INTEGER_CSTs in their native precision. This is just as efficient, and makes it clearer that a deliberate choice is being made to treat the tree as a wide_int in its native precision. This also removes the inconsistency that a) INTEGER_CSTs in their native precision can be used without an accessor but must use wi:: functions instead of C++ operators b) the other forms need an explicit accessor but the result can be used with C++ operators. It also helps with SVE, where there's the additional possibility that the tree could be a runtime value. 2017-10-10 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * wide-int.h (wide_int_ref_storage): Make host_dependent_precision a template parameter.

2017-09-25[PR82155] Fix crash in dwarf2out_abstract_functionPierre-Marie de Rodat1-2/+8
This patch is an attempt to fix the crash reported in PR82155. When generating a C++ class method for a class that is itself nested in a class method, dwarf2out_early_global_decl currently leaves the existing context DIE as it is if it already exists. However, it is possible that this call happens at a point where this context DIE is just a declaration that is itself not located in its own context. From there, if dwarf2out_early_global_decl is not called on any of the FUNCTION_DECL in the context chain, DIEs will be left badly scoped and some (such as the nested method) will be removed by the type pruning machinery. As a consequence, dwarf2out_abstract_function will will crash when called on the corresponding DECL because it asserts that the DECL has a DIE. This patch fixes this crash making dwarf2out_early_global_decl process context DIEs the same way we process abstract origins for FUNCTION_DECL: if the corresponding DIE exists but is only a declaration, call dwarf2out_decl anyway on it so that it is turned into a more complete DIE and so that it is relocated in the proper context.

2017-09-21enable handling of -gno- command-line options as negated prefixesAlexandre Oliva1-1/+0
This patch that adds -g to the set of negatable prefixes along with -f, -m and -W. Besides the mapping from -gno- to negated -g in option_map and adding g to the [fmW] matches for negatable options, I had to introduce gno- as an remapping prefix, for the option searching machinery to backtrack to and recognize as a remapping prefix, instead of backtracking to -g and stopping at it as if no-* was its Joined argument. Adding such remapping prefixes to preempt further backtracking can be accomplished by introducing the prefix as an Undocumented option with a Joined argument and without Driver, Target, Common, or any language-specific option. Whenever we match such a fake options prefix, we abandon further backtracking (it matches, after all), but find_opt returns the same code it would if it hadn't found any match, so that we resort to option mapping. I've arranged for such remapping prefixes to not be considered when looking for and suggesting a correct spelling for misspelled options. While testing that, I found a few -W-started options that were not marked as RejectNegative but should (-Wno-a, is not something we'd like to suggest ;-) I've also marked as such -g-started options that it makes no sense to negate, and removed the explicit -gno- ones, allowing their opposites to be negated. for gcc/ChangeLog * common.opt (Wa, Wl, Wp, g, gz=): Add RejectNegative.

2017-08-30[66/77] Use scalar_mode for constant integersRichard Sandiford1-3/+4
This patch treats the mode associated with an integer constant as a scalar_mode. We can't use the more natural-sounding scalar_int_mode because we also use (const_int 0) for bounds-checking modes. (It might be worth adding a bounds-specific code instead, but that's for another day.) This exposes a latent bug in simplify_immed_subreg, which for vectors of CONST_WIDE_INTs would pass the vector mode rather than the element mode to rtx_mode_t. I think the: /* We can get a 0 for an error mark. */ || GET_MODE_CLASS (mode) == MODE_VECTOR_INT || GET_MODE_CLASS (mode) == MODE_VECTOR_FLOAT in immed_double_const is dead. trunc_int_mode (via gen_int_mode) would go on to ICE if the mode fitted in a HWI, and surely plenty of other code would be confused to see a const_int be interpreted as a vector. We should instead be using CONST0_RTX (mode) if we need a safe constant for a particular mode. We didn't try to make these functions take scalar_mode arguments because in many cases that would be too invasive at this stage. Maybe it would become feasible in future. Also, the long-term direction should probably be to add modes to constant integers rather than have then as VOIDmode odd-ones-out. That would remove the need for rtx_mode_t and thus remove the question whether they should use scalar_int_mode, scalar_mode or machine_mode. The patch also uses scalar_mode for the CONST_DOUBLE handling in loc_descriptor. In that case the mode can legitimately be either floating-point or integral. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * emit-rtl.c (immed_double_const): Use is_a <scalar_mode> instead of separate mode class checks.

2017-08-30[29/77] Make some *_loc_descriptor helpers take scalar_int_modeRichard Sandiford1-22/+21
The *_loc_descriptor routines for clz, popcount, bswap and rotate all required SCALAR_INT_MODE_P. This patch moves the checks into the caller (mem_loc_descriptor) so that the types of the mode parameters can be scalar_int_mode instead of machine_mode. The MOD handling in mem_loc_descriptor is also specific to scalar integer modes. Adding an explicit check allows typed_binop to take a scalar_int_mode too. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * dwarf2out.c (typed_binop): Change mode parameter to scalar_int_mode.

2017-08-30[28/77] Use is_a <scalar_int_mode> for miscellaneous types of testRichard Sandiford1-16/+14
This patch adds is_a <scalar_int_mode> checks to various places that were explicitly or implicitly restricted to integers already, in cases where adding an explicit is_a <scalar_int_mode> is useful for later patches. In simplify_if_then_else, the: GET_MODE (XEXP (XEXP (t, 0), N)) expressions were equivalent to: GET_MODE (XEXP (t, 0)) due to the type of operation. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * combine.c (sign_extend_short_imm): Add is_a <scalar_int_mode> checks.

2017-08-30[21/77] Replace SCALAR_INT_MODE_P checks with is_a <scalar_int_mode>Richard Sandiford1-93/+94
This patch replaces checks of "SCALAR_INT_MODE_P (...)" with "is_a <scalar_int_mode> (..., &var)" in cases where it becomes useful to refer to the mode as a scalar_int_mode. It also replaces some checks for the two constituent classes (MODE_INT and MODE_PARTIAL_INT). The patch also introduces is_a <scalar_int_mode> checks for some uses of HWI_COMPUTABLE_MODE_P, which is a subcondition of SCALAR_INT_MODE_P. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * wide-int.h (int_traits<unsigned char>) New class.
