2020-11-09Clean up irange self tests.Aldy Hernandez1-0/+1
Currently we have all the irange and range-op tests in range-op.cc. This patch splits them up into the appropriate file (irange tests in value-range.cc and range-op tests in range-op.cc). The patch also splits up the tests themselves by functionality. It's not perfect, but significantly better than the mess we had. gcc/ChangeLog: * function-tests.c (test_ranges): Call range_op_tests. * range-op.cc (build_range3): Move to value-range.cc. (range3_tests): Same. (int_range_max_tests): Same. (multi_precision_range_tests): Same. (range_tests): Same. (operator_tests): Split up... (range_op_tests): Split up... (range_op_cast_tests): ...here. (range_op_lshift_tests): ...here. (range_op_rshift_tests): ...here. (range_op_bitwise_and_tests): ...here. * selftest.h (range_op_tests): New. * value-range.cc (build_range3): New. (range_tests_irange3): New. (range_tests_int_range_max): New.

2018-08-06Fix memory leak in selftest::test_expansion_to_rtlDavid Malcolm1-0/+1
"make selftest-valgrind" shows: 187 bytes in 1 blocks are definitely lost in loss record 567 of 669 at 0x4A081D4: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) by 0x1F08260: xcalloc (xmalloc.c:162) by 0xB24F32: init_emit() (emit-rtl.c:5843) by 0xC10080: prepare_function_start() (function.c:4803) by 0xC10254: init_function_start(tree_node*) (function.c:4877) by 0x1CDF92A: selftest::test_expansion_to_rtl() (function-tests.c:595) by 0x1CE007C: selftest::function_tests_c_tests() (function-tests.c:676) by 0x1E010E7: selftest::run_tests() (selftest-run-tests.c:98) by 0x1062D1E: toplev::run_self_tests() (toplev.c:2225) by 0x1062F40: toplev::main(int, char**) (toplev.c:2303) by 0x1E5B90A: main (main.c:39) The allocation in question is: crtl->emit.regno_pointer_align = XCNEWVEC (unsigned char, crtl->emit.regno_pointer_align_length); This patch fixes this leak (and makes the output of "make selftest-valgrind" clean) by calling free_after_compilation at the end of the selftest in question. gcc/ChangeLog: * function-tests.c (selftest::test_expansion_to_rtl): Call free_after_compilation.

2017-07-02Reorganise machmode.h headersRichard Sandiford1-4/+0
This patch splits the auto-generated inline functions out of insn-modes.h and puts them in a new header file, insn-modes-inline.h. It also makes coretypes.h include these files directly, rather than indirectly via machmode.h. This in turn allows insn-modes-inline.h and machmode.h to come later in the include list, after wide-int.h. This is useful for later patches. insn-modes.h itself still needs to come first, since it provides configuration information like MAX_BITSIZE_MODE_ANY_INT, which is used to control the size of a wide_int. The patch also makes the generator files include machmode.h via coretypes.h. Previously they did it by more indirect means. Finally, the patch makes wide-int-print.h available via coretypes.h too. There didn't seem to be any reason to force only the print routines to be included directly, and it would be painful to extend that approach to the SVE patches.
