2021-09-17PR c/102245: Disable sign-changing optimization for shifts by zero.Roger Sayle2-2/+39
Respecting Jakub's suggestion that it may be better to warn-on-valid for "if (x << 0)" as the author might have intended "if (x < 0)" [which will also warn when x is _Bool], the simplest way to resolve this regression is to disable the recently added fold transformation for shifts by zero; these will be optimized later (elsewhere). Guarding against integer_zerop is the simplest of three alternatives; the second being to only apply this transformation to GIMPLE and not GENERIC, and the third (potentially) being to explicitly handle shifts by zero here, with an (if cond then else), optimizing the expression to a convert, but awkwardly duplicating a more general transformation earlier in match.pd's shift simplifications. 2021-09-17 Roger Sayle <roger@nextmovesoftware.com> gcc/ChangeLog PR c/102245 * match.pd (shift optimizations): Disable recent sign-changing optimization for shifts by zero, these will be folded later. gcc/testsuite/ChangeLog PR c/102245 * gcc.dg/Wint-in-bool-context-4.c: New test case.
2021-09-17rs6000: Move __builtin_mffsl to the [always] stanzaBill Schmidt1-3/+6
I over-restricted use of __builtin_mffsl, since I was unaware that it automatically uses mffs when mffsl is not available.

2021-09-17Fix PR rtl-optimization/102306Eric Botcazou2-0/+29
This is a duplication of volatile loads introduced during GCC 9 development by the 2->2 mechanism of the RTL combiner. There is already a substantial checking for volatile references in can_combine_p but it implicitly assumes that the combination reduces the number of instructions, which is of course not the case here. So the fix teaches try_combine to abort the combination when it is about to make a copy of volatile references to preserve them. gcc/ PR rtl-optimization/102306 * combine.c (try_combine): Abort the combination if we are about to duplicate volatile references. gcc/testsuite/ * gcc.target/sparc/20210917-1.c: New test.

This avoids using native_interpret_type when we cannot do it with the original type of the variable, instead use an integer type for the initialization and side-step the size limitation of native_interpret_int. 2021-09-16 Richard Biener <rguenther@suse.de> PR middle-end/102360 * internal-fn.c (expand_DEFERRED_INIT): Make pattern-init of non-memory more robust. * g++.dg/pr102360.C: New testcase.
2021-09-16sparc: Add scheduling information for LEON5Daniel Cederman7-22/+220
The LEON5 can often dual issue instructions from the same 64-bit aligned double word if there are no data dependencies. Add scheduling information to avoid scheduling unpairable instructions back-to-back. gcc/ChangeLog: * config/sparc/sparc-opts.h (enum sparc_processor_type): Add LEON5 * config/sparc/sparc.c (struct processor_costs): Add LEON5 costs (leon5_adjust_cost): Increase cost of store with data dependency on ALU instruction and FPU anti-dependencies. (sparc_option_override): Add LEON5 costs (sparc_adjust_cost): Add LEON5 cost adjustments * config/sparc/sparc.h: Add LEON5 * config/sparc/sparc.md: Include LEON5 scheduling information * config/sparc/sparc.opt: Add LEON5 * doc/invoke.texi: Add LEON5 * config/sparc/leon5.md: New file.
2021-09-16sparc: Add NOP in stack_protect_set32 if sparc_fix_b2bst enabledDaniel Cederman1-2/+8
This is needed to prevent the Store -> (Non-store or load) -> Store sequence. gcc/ChangeLog: * config/sparc/sparc.md (stack_protect_set32): Add NOP to prevent sensitive sequence for B2BST errata workaround.
2021-09-16sparc: Prevent atomic instructions in beginning of functions for UT700Daniel Cederman1-0/+11
A call to the function might have a load instruction in the delay slot and a load followed by an atomic function could cause a deadlock. gcc/ChangeLog: * config/sparc/sparc.c (sparc_do_work_around_errata): Do not begin functions with atomic instruction in the UT700 errata workaround.
2021-09-16sparc: Skip all empty assembly statementsDaniel Cederman1-14/+21
This version detects multiple empty assembly statements in a row and also detects non-memory barrier empty assembly statements (__asm__("")). It can be used instead of next_active_insn(). gcc/ChangeLog: * config/sparc/sparc.c (next_active_non_empty_insn): New function that returns next active non empty assembly instruction. (sparc_do_work_around_errata): Use new function.
