2020-11-13d: Fix ICE in finish_thunk (PR97644)Iain Buclaw1-0/+9
Because this what the upstream reference compiler did, thunks for the D front-end were associated with the class definition, so were forced code-gen even if the target function was extern. This has now been changed so there are now only generated if there is a function definition, fixing the ICE that occurred in PR 97644, which was caused by calling expand_thunk() early. gcc/d/ChangeLog: PR d/97644 * dmd/MERGE: Merge upstream dmd 95044d8e4. * d-target.cc (TargetCPP::thunkMangle): New function. * decl.cc (finish_thunk): Don't force expand thunks for external functions. (make_thunk): Emit thunks only if the function has a definition. Generate correct mangling for thunks to C++ classes. gcc/testsuite/ChangeLog: * gdc.dg/pr92216.d: Update scan-assember.

2020-08-31d: Fix ICEs in the front-end when pointer size is 16-bit.Iain Buclaw1-3/+0
In the lowering of `bt*' intrinsics, some integer constants had mismatched types, and bitsize was set to the wrong value. In base_vtable_offset, the base offset value was calculated incorrectly. The TypeInfo_Class object is comprised of 18 pointers and 1 uint field, so now the internal classinfo type size is used instead. gcc/d/ChangeLog: * d-target.cc (Target::_init): Don't set classinfosize. * d-tree.h (base_vtable_offset): Move under typeinfo.cc section. * decl.cc (base_vtable_offset): Move to... * typeinfo.cc (base_vtable_offset): ...here.

2019-11-13Add C2x *_NORM_MAX constants to <float.h>.Joseph Myers1-1/+1
C2x adds <float.h> constants FLT_NORM_MAX, DBL_NORM_MAX and LDBL_NORM_MAX. These are for the maximum "normalized" finite floating-point number, where the given definition of normalized is that all possible values with MANT_DIG significand digits (leading one not zero) can be represented with that exponent. The effect of that definition is that these macros are the same as the corresponding MAX macros for all formats except IBM long double, where the NORM_MAX value has exponent 1 smaller than the MAX one so that all 106 digits can be 1. This patch adds those macros to GCC. They are only defined for float, double and long double; C2x does not include such macros for DFP types, and while the integration of TS 18661-3 into C2x has not yet occurred, the draft proposed text does not add them for the _FloatN / _FloatNx types (where they would always be the same as the MAX macros). Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested compilation of the new test for powerpc-linux-gnu to confirm the check of LDBL_NORM_MAX in the IBM long double case does get properly optimized out. gcc: * ginclude/float.c [__STDC_VERSION__ > 201710L] (FLT_NORM_MAX, DBL_NORM_MAX, LDBL_NORM_MAX): Define. * real.c (get_max_float): Add norm_max argument. * real.h (get_max_float): Update prototype. * builtins.c (fold_builtin_interclass_mathfn): Update calls to get_max_float. gcc/c-family: * c-cppbuiltin.c (builtin_define_float_constants): Also define NORM_MAX constants. Update call to get_max_float.
