2018-02-09[IEPM] Introduce inline entry point markersAlexandre Oliva1-0/+9
Output DW_AT_entry_pc based on markers. Introduce DW_AT_GNU_entry_view as a DWARF extension. If views are enabled are we're not in strict compliance mode, output DW_AT_GNU_entry_view if it might be nonzero.

2018-01-03poly_int: TYPE_VECTOR_SUBPARTSRichard Sandiford1-6/+11
This patch changes TYPE_VECTOR_SUBPARTS to a poly_uint64. The value is encoded in the 10-bit precision field and was previously always stored as a simple log2 value. The challenge was to use this 10 bits to encode the number of elements in variable-length vectors, so that we didn't need to increase the size of the tree. In practice the number of vector elements should always have the form N + N * X (where X is the runtime value), and as for constant-length vectors, N must be a power of 2 (even though X itself might not be). The patch therefore uses the low 8 bits to encode log2(N) and bit 8 to select between constant-length and variable-length vectors. Targets without variable-length vectors continue to use the old scheme. A new valid_vector_subparts_p function tests whether a given number of elements can be encoded. This is false for the vector modes that represent an LD3 or ST3 vector triple (which we want to treat as arrays of vectors rather than single vectors). Most of the patch is mechanical; previous patches handled the changes that weren't entirely straightforward. 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree.h (TYPE_VECTOR_SUBPARTS): Turn into a function and handle polynomial numbers of units.

2017-12-20poly_int: get_ref_base_and_extentRichard Sandiford1-5/+5
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.

This patch adds a tree representation for poly_ints. Unlike the rtx version, the coefficients are INTEGER_CSTs rather than plain integers, so that we can easily access them as poly_widest_ints and poly_offset_ints. The patch also adjusts some places that previously relied on "constant" meaning "INTEGER_CST". It also makes sure that the TYPE_SIZE agrees with the TYPE_SIZE_UNIT for vector booleans, given the existing: /* Several boolean vector elements may fit in a single unit. */ if (VECTOR_BOOLEAN_TYPE_P (type) && type->type_common.mode != BLKmode) TYPE_SIZE_UNIT (type) = size_int (GET_MODE_SIZE (type->type_common.mode)); else TYPE_SIZE_UNIT (type) = int_const_binop (MULT_EXPR, TYPE_SIZE_UNIT (innertype), size_int (nunits)); 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/generic.texi (POLY_INT_CST): Document. * tree.def (POLY_INT_CST): New tree code. * treestruct.def (TS_POLY_INT_CST): New tree layout. * tree-core.h (tree_poly_int_cst): New struct.

2017-12-19[SFN] start rtl block with label, then markersAlexandre Oliva1-8/+4
Emitting markers before labels turned out to not be worth the trouble. The markers outside BBs confuse the ebb scheduler, and they don't add any useful information.

2017-12-12[SFN] not-quite-boilerplate changes in preparation to introduce nonbind markersAlexandre Oliva1-4/+20
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.

2017-12-12[SFN] boilerplate changes in preparation to introduce nonbind markersAlexandre Oliva1-4/+4
This patch introduces a number of new macros and functions that will be used to distinguish between different kinds of debug stmts, insns and notes, namely, preexisting debug bind ones and to-be-introduced nonbind markers. In a seemingly mechanical way, it adjusts several uses of the macros and functions, so that they refer to narrower categories when appropriate. These changes, by themselves, should not have any visible effect in the compiler behavior, since the upcoming debug markers are never created with this patch alone. for gcc/ChangeLog * gimple.h (enum gimple_debug_subcode): Add GIMPLE_DEBUG_BEGIN_STMT.

2017-10-23Convert STARTING_FRAME_OFFSET to a hookRichard Sandiford1-1/+1
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...

2017-10-22Make more use of GET_MODE_UNIT_PRECISIONRichard Sandiford1-4/+10
This patch is like the earlier GET_MODE_UNIT_SIZE one, but for precisions rather than sizes. There is one behavioural change in expand_debug_expr: we shouldn't use lowpart subregs for non-scalar truncations, since that would just reinterpret some of the scalars and drop the rest. (This probably doesn't trigger in practice.) Using TRUNCATE is fine for scalars, since simplify_gen_unary knows when a subreg can be used. 2017-10-22 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * cfgexpand.c (expand_debug_expr): Use GET_MODE_UNIT_PRECISION.

2017-10-20Add generic part for Intel CET enabling. The spec is available atIgor Tsimbalist1-0/+16
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf A proposal is to introduce a target independent flag -fcf-protection=[none|branch|return|full] with a semantic to instrument a code to control validness or integrity of control-flow transfers using jump and call instructions. The main goal is to detect and block a possible malware execution through transfer the execution to unknown target address. Implementation could be either software or target based. Any target platforms can provide their implementation for instrumentation under this option. The compiler should instrument any control-flow transfer points in a program (ex. call/jmp/ret) as well as any landing pads, which are targets of control-flow transfers. A new 'nocf_check' attribute is introduced to provide hand tuning support. The attribute directs the compiler to skip a call to a function and a function's landing pad from instrumentation. The attribute can be used for function and pointer to function types, otherwise it will be ignored. Currently all platforms except i386 will report the error and do no instrumentation. i386 will provide the implementation based on a specification published by Intel for a new technology called Control-flow Enforcement Technology (CET). gcc/c-family/ * c-attribs.c (handle_nocf_check_attribute): New function.

2017-09-14Store VECTOR_CST_NELTS directly in tree_nodeRichard Sandiford1-4/+4
Previously VECTOR_CST_NELTS (t) read the number of elements from TYPE_VECTOR_SUBPARTS (TREE_TYPE (t)). There were two ways of handling this with variable TYPE_VECTOR_SUBPARTS: either forcibly convert the number to a constant (which is doable) or store the number directly in the VECTOR_CST. The latter seemed better, since it involves less pointer chasing and since the tree_node u field is otherwise unused for VECTOR_CST. It would still be easy to switch to the former in future if we need to free up the field for someting else. The patch also changes various bits of VECTOR_CST code to use VECTOR_CST_NELTS instead of TYPE_VECTOR_SUBPARTS when iterating over VECTOR_CST_ELTs. Also, when the two are checked for equality, the patch prefers to read VECTOR_CST_NELTS (which must be constant) and check against TYPE_VECTOR_SUBPARTS, instead of the other way around. 2017-09-14 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-core.h (tree_base::u): Add an "nelts" field.

2017-09-04PR82045: Avoid passing machine modes through "..."Richard Sandiford1-1/+1
PR82045 is about a bootstrap failure on sparc-sun-solaris2.11. The problem was that we were passing the new machine_mode wrapper classes through "..." to emit_library_call(_value), which then read them back as ints instead. The simplest fix seemed to be replace "..." with an array of rtx_mode_ts, then provide wrappers for the common cases. This bulks out rtl.h a bit, but it does make things a bit more typesafe. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR bootstrap/82045 * rtl.h (emit_library_call_value_1): Declare.
