2017-09-04PR82045: Avoid passing machine modes through "..."Richard Sandiford43-199/+387
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.

2017-09-01combine: Fix for PR82024Segher Boessenkool2-5/+21
With the testcase in the PR, with all the command line options mentioned there, a (comparison) instruction becomes dead in fwprop1 but is not deleted until all the way in rtl_dce. Before combine this insn look like: 20: flags:CC=cmp(r106:DI,0xffffffffffffffff) REG_DEAD r106:DI REG_UNUSED flags:CC REG_EQUAL cmp(0,0xffffffffffffffff) (note the only output is unused). Combining some earlier insns gives 13: r106:DI=0 14: r105:DI=r101:DI+r103:DI 14+13+20 then gives (parallel [ (set (reg:CC 17 flags) (compare:CC (const_int 0 [0]) (const_int -1 [0xffffffffffffffff]))) (set (reg:DI 105) (plus:DI (reg/v:DI 101 [ e ]) (reg:DI 103))) ]) which doesn't match; but the set of flags is dead, so combine makes the set of r105 the whole new instruction, which it then places at i3. But that is wrong, because r105 is used after i2 but before i3! We forget to check for that in this case. This patch fixes it. PR rtl-optimization/82024 * combine.c (try_combine): If the combination result is a PARALLEL, and we only need to retain the SET in there that would be placed at I2, check that we can place that at I3 instead, before doing so.

2017-09-01Fix excess precision handling of compound assignments (PR c/82071).Joseph Myers4-11/+99
PR c/82071 reports how compound assignment operators such as += handle excess precision inconsistently with the same operation done with a plain assignment and binary operator. There were (at least) two problems with how compound assignments handled excess precision. The EXCESS_PRECISION_EXPR for an argument with excess precision was removed too early, resulting in build_binary_op being called with an rhs operand whose type reflected the evaluation format, so not having sufficient information to achieve the intended semantics in all cases, and then the code called c_fully_fold on the results of build_binary_op without allowing for the possibility of an EXCESS_PRECISION_EXPR as the result, so leading to double rounding of the result (first to its semantic type, then to the type of the LHS of the assignment) instead of the intended single rounding. This patch fixes those problems by keeping EXCESS_PRECISION_EXPRs further through build_modify_expr (and build_atomic_assign which it calls) and only removing them locally where appropriate. Note that while this patch should achieve *consistency*, that's consistency with the understanding of C99 semantics that I originally intended to implement. For the particular case in the testcase, C11 semantics (from N1531) differ from that understanding of C99 semantics, in that an implicit conversion of an integer to floating point can have excess precision. I intend to implement those C11 semantics separately (conditional on flag_isoc11) (which will also mean that building conditional expressions can produce a result with excess precision even when the arguments lack excess precision, where previously it could not), and not to close the bug until that is also done. Tested for x86_64-pc-linux-gnu. PR c/82071 gcc/c: * c-typeck.c (build_atomic_assign): Handle argument with excess precision. Ensure any EXCESS_PRECISION_EXPR is present in argument passed to build_binary_op and convert_for_assignment but not for call to c_fully_fold.
