* Clang :: Sema/wchar.c has long been failing on Solaris:Rainer Orth2019-06-171-1/+6

This is called for by SCD 2.4.1, p. 6-83, Figure 6-65 (32-bit) and p. 6P-10, Figure 6.38 (64-bit). */ #undef WCHAR_TYPE #define WCHAR_TYPE (TARGET_64BIT ? "int" : "long int") The following patch implements this, and at the same time corrects the wint_t definition which is the same: /* Same for wint_t. See SCD 2.4.1, p. 6-83, Figure 6-66 (32-bit). There's no corresponding 64-bit definition, but this is what Solaris 8 <iso/wchar_iso.h> uses. */ #undef WINT_TYPE #define WINT_TYPE (TARGET_64BIT ? "int" : "long int") Clang :: Preprocessor/wchar_t.c and Clang :: Sema/format-strings.c need to be adjusted to account for that. Tested on i386-pc-solaris2.11, x86_64-pc-solaris2.11, and x86_64-pc-linux-gnu. Differential Revision: https://reviews.llvm.org/D62944 llvm-svn: 363612
* Driver: hoist the `wchar_t` handling to the driverSaleem Abdulrasool2017-10-061-0/+113
Move the logic for determining the `wchar_t` type information into the driver. Rather than passing the single bit of information of `-fshort-wchar` indicate to the frontend the desired type of `wchar_t` through a new `-cc1` option of `-fwchar-type` and indicate the signedness through `-f{,no-}signed-wchar`. This replicates the current logic which was spread throughout Basic into the `RenderCharacterOptions`. Most of the changes to the tests are to ensure that the frontend uses the correct type. Add a new test set under `test/Driver/wchar_t.c` to ensure that we calculate the proper types for the various cases. llvm-svn: 315126
