2021-05-04Remove CC0Segher Boessenkool1-1/+2
This removes CC0 and all directly related infrastructure. CC_STATUS, CC_STATUS_MDEP, CC_STATUS_MDEP_INIT, and NOTICE_UPDATE_CC are deleted and poisoned. CC0 is only deleted (some targets use that name for something else). HAVE_cc0 is automatically generated, and we no longer will do that after this patch. CC_STATUS_INIT is suggested in final.c to also be useful for ports that are not CC0, and at least arm seems to use it for something. So I am leaving that alone, but most targets that have it could remove it. 2021-05-04 Segher Boessenkool <segher@kernel.crashing.org> * caller-save.c: Remove CC0. * cfgcleanup.c: Remove CC0. * cfgrtl.c: Remove CC0. * combine.c: Remove CC0. * compare-elim.c: Remove CC0. * conditions.h: Remove CC0. * config/h8300/h8300.h: Remove CC0. * config/h8300/h8300-protos.h: Remove CC0. * config/h8300/peepholes.md: Remove CC0. * config/i386/x86-tune-sched.c: Remove CC0. * config/m68k/m68k.c: Remove CC0. * config/rl78/rl78.c: Remove CC0. * config/sparc/sparc.c: Remove CC0. * config/xtensa/xtensa.c: Remove CC0.

2021-04-29Add parallelism support to gcov for MinGW platformsEric Botcazou1-0/+4
If you attempt a profiled bootstrap on the MinGW platforms with -jN, N > 1, it miserably fails because of profile mismatches all over the place, the reason being that gcov has no support for parallelism on these platforms. libgcc/ * libgcov.h: For the target, define GCOV_LOCKED_WITH_LOCKING if __MSVCRT__ and, for the host, define it if HOST_HAS_LK_LOCK. * libgcov-driver.c: Add directives if GCOV_LOCKED_WITH_LOCKING. gcc/ * configure.ac: Check for the presence of sys/locking.h header and for whether _LK_LOCK is supported by _locking. * configure: Regenerate. * config.in: Likewise. * gcov-io.h: Define GCOV_LOCKED_WITH_LOCKING if HOST_HAS_LK_LOCK. * gcov-io.c (gcov_open): Add support for GCOV_LOCKED_WITH_LOCKING. * system.h: Include <sys/locking.h> if HAVE_SYS_LOCKING_H.

2020-12-17Add an alternative splay tree implementationRichard Sandiford1-0/+3
We already have two splay tree implementations: the old C one in libiberty and a templated reimplementation of it in typed-splay-tree.h. However, they have some drawbacks: - They hard-code the assumption that nodes should have both a key and a value, which isn't always true. - They use the two-phase method of lookup, and so nodes need to store a temporary back pointer. We can avoid that overhead by using the top-down method (as e.g. the bitmap tree code already does). - The tree node has to own the key and the value. For some use cases it's more convenient to embed the tree links in the value instead. Also, a later patch wants to use splay trees to represent an adaptive total order: the splay tree itself records whether node N1 is less than node N2, and (in the worst case) comparing nodes is a splay operation. This patch therefore adds an alternative implementation. The main features are: - Nodes can optionally point back to their parents. - An Accessors class abstracts accessing child nodes and (where applicable) parent nodes, so that the information can be embedded in larger data structures. - There is no fixed comparison function at the class level. Instead, individual functions that do comparisons take a comparison function argument. - There are two styles of comparison function, optimised for different use cases. (See the comments in the patch for details.) - It's possible to do some operations directly on a given node, without knowing whether it's the root. This includes the comparison use case described above. This of course has its own set of drawbacks. It's really providing splay utility functions rather than a true ADT, and so is more low-level than the existing routines. It's mostly geared for cases in which the client code wants to participate in the splay operations to some extent. gcc/ * Makefile.in (OBJS): Add splay-tree-utils.o. * system.h: Include <array> when INCLUDE_ARRAY is defined. * selftest.h (splay_tree_cc_tests): Declare. * selftest-run-tests.c (selftest::run_tests): Run splay_tree_cc_tests. * splay-tree-utils.h: New file. * splay-tree-utils.tcc: Likewise. * splay-tree-utils.cc: Likewise.
2020-11-12system: Add WARN_UNUSED_RESULTMarek Polacek1-0/+6
I'd like to have the option of marking functions with __attribute__ ((__warn_unused_result__)), so this patch adds a macro. And use it for maybe_wrap_with_location, it's always a bug if the return value is not used, which happened to me and got me confused. gcc/ChangeLog: * system.h (WARN_UNUSED_RESULT): Define for GCC >= 3.4. * tree.h (maybe_wrap_with_location): Add WARN_UNUSED_RESULT.

2020-08-14vec: Fix bootstrap on i686-linux, 32-bit darwin and AIXJakub Jelinek1-0/+1
As mentioned earlier, embedded_size is broken on vecs of long long, double etc. on some platforms, which breaks bootstrap. E.g. on i686-linux, the problem is mostly with older GCC versions being used as stage1 compiler (GCC 4.8 to 7.* in particular), because alignas (long long) makes U 64-bit aligned, while when long long m_vecdata[1]; is in vec, it is only 32-bit aligned. We've tried various ways and the following one seems to work, use the old way (offsetof (vec, m_vecdata)) for non-class types as well as standard layout class types, i.e. whenever offsetof is guaranteed to work, and for others use the new day (in that case we don't run into problems with long long or other scalar types and for the structure layout there is just a struct with a given alignment. 2020-08-14 Jakub Jelinek <jakub@redhat.com> Jonathan Wakely <jwakely@redhat.com> * system.h: Include type_traits. * vec.h (vec<T, A, vl_embed>::embedded_size): Use offsetof and asserts on vec_stdlayout, which is conditionally a vec (for standard layout T) and otherwise vec_embedded.

2020-07-02Redefine NULL to nullptrIlya Leoshkevich1-0/+10
Bootstrap with musl libc fails with numerous "missing sentinel in function call" errors. This is because musl defines NULL as 0L for C++, but gcc requires sentinel value to be a pointer or __null. Jonathan Wakely says: To be really safe during stage 1, GCC should not use NULL as a pointer sentinel in C++ code anyway. The bootstrap compiler could define it to 0 or 0u, neither of which is guaranteed to be OK to pass as a varargs sentinel where a null pointer is expected. Any of (void*)0 or (void*)NULL or nullptr would be safe. While it is possible to fix this by replacing NULL sentinels with nullptrs, such approach would generate backporting conflicts, therefore simply redefine NULL to nullptr at the end of system.h, where it would not confuse system headers. gcc/ChangeLog: 2020-06-30 Ilya Leoshkevich <iii@linux.ibm.com> PR bootstrap/95700 * system.h (NULL): Redefine to nullptr.

2017-10-23Convert STARTING_FRAME_OFFSET to a hookRichard Sandiford1-1/+2
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...

2017-09-25Turn CONSTANT_ALIGNMENT into a hookRichard Sandiford1-1/+1
The definition: #define CONSTANT_ALIGNMENT(EXP, ALIGN) \ (TREE_CODE (EXP) == STRING_CST \ && (ALIGN) < BITS_PER_WORD ? BITS_PER_WORD : (ALIGN)) was very common, so the patch adds a canned definition for that, called constant_alignment_word_strings. Some ports had a variation that used a port-local FASTEST_ALIGNMENT instead of BITS_PER_WORD; the patch uses constant_alignment_word_strings if FASTEST_ALIGNMENT was always BITS_PER_WORD and a port-local hook function otherwise. 2017-09-25 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (constant_alignment): New hook. * defaults.h (CONSTANT_ALIGNMENT): Delete. * doc/tm.texi.in (CONSTANT_ALIGNMENT): Replace with...

2017-09-13Turn SECONDARY_MEMORY_NEEDED_MODE into a target hookRichard Sandiford1-1/+1
This includes a change to LRA. Previously the code was: if (sclass == NO_REGS && dclass == NO_REGS) return false; #ifdef SECONDARY_MEMORY_NEEDED if (SECONDARY_MEMORY_NEEDED (sclass, dclass, GET_MODE (src)) #ifdef SECONDARY_MEMORY_NEEDED_MODE && ((sclass != NO_REGS && dclass != NO_REGS) || GET_MODE (src) != SECONDARY_MEMORY_NEEDED_MODE (GET_MODE (src))) #endif ) { *sec_mem_p = true; return false; } #endif in which the positioning of the second ifdef meant that defining SECONDARY_MEMORY_NEEDED_MODE to its default value was not a no-op: without a definition, we would consider using secondary reloads for mem<-reg and reg<-mem reloads even if the secondary memory has the same mode as the original mem, while defining it would avoid this. The latter behaviour seems correct. The default is different for reload and LRA. For LRA the default is to use the original mode, while reload promotes smaller-than-word integral modes to word mode: if (GET_MODE_BITSIZE (mode) < BITS_PER_WORD && INTEGRAL_MODE_P (mode)) mode = mode_for_size (BITS_PER_WORD, GET_MODE_CLASS (mode), 0).require (); Some of the ports that have switched to LRA seemed to have SECONDARY_MEMORY_NEEDED_MDOEs based on the old reload definition, and still referred to the reload.c:get_secondary_mem function in the comments. The patch just keeps them as-is. 2017-09-13 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * target.def (secondary_memory_needed_mode): New hook: * targhooks.c (default_secondary_memory_needed_mode): Declare. * targhooks.h (default_secondary_memory_needed_mode): New function. * doc/tm.texi.in (SECONDARY_MEMORY_NEEDED_MODE): Replace with...

2017-09-04Turn HARD_REGNO_CALL_PART_CLOBBERED into a target hookRichard Sandiford1-1/+2
The SVE patches change the size of a machine_mode from a compile-time constant to a runtime invariant. However, target-specific code can continue to treat the modes as constant-sized if the target only has constant-sized modes. The main snag with this approach is that target-independent code still uses macros from the target .h file. This patch is one of several that converts a target macro to a hook. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * target.def (hard_regno_call_part_clobbered): New hook. * doc/tm.texi.in (HARD_REGNO_CALL_PART_CLOBBERED): Replace with...

2017-08-30[3/77] Allow machine modes to be classesRichard Sandiford1-0/+6
This patch makes various changes that allow modes like SImode to be classes rather than enums. Firstly, it adds inline functions for all mode size properties, with the macros being simple wrappers around them. This is necessary for the __builtin_constant_p trick to continue working effectively when the mode arguments are slightly more complex (but still foldable at compile time). These inline functions are trivial and heavily used. There's not much point keeping them out-of-line at -O0: if anything it would make debugging harder rather than easier, and it would also slow things down. The patch therefore marks them as "always_inline", if that's available. Later patches use this approach too. Using inline functions means that it's no longer possible to pass an int to GET_MODE_PRECISION etc. The Fortran and powerpcspe-c.c parts are needed to avoid instances of that. The patch continues to use enums for gencondmd.c, so that more mode comparisons are integer constant expressions when checking for always-true or always-false conditions. This is the only intended use of USE_ENUM_MODES. The patch also enforces the previous replacement of case statements by defining modes as: #define FOOmode ((void) 0, E_FOOmode) This adds no overhead but makes sure that new uses of "case FOOmode:" don't accidentally creep in when FOOmode has no specific class associated with it. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * genconditions.c (write_header): Add a "#define USE_ENUM_MODES". * genmodes.c (emit_insn_modes_h): Define FOOmode to E_FOOmode if USE_ENUM_MODES is defined and to ((void) 0, E_FOOmode) otherwise. * machmode.h (mode_size): Move earlier in file.
