* [clang][Darwin] Refactor header search path logic into the driverLouis Dionne2019-05-211-6/+0
| | | | | | | | | | | | | | | | | | | | | | | Summary: This commit moves the logic for determining system, resource and C++ header search paths from CC1 to the driver. This refactor has already been made for several platforms, but Darwin had been left behind. This refactor tries to implement the previous search path logic with perfect accuracy. In particular, the order of all include paths inside CC1 and all paths that were skipped because nonexistent are conserved after the refactor. This change was also tested against a code base of significant size and revealed no problems.

* Fixed frontend clang tests in windows read-only containerStella Stamenova2019-01-252-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: When mounting LLVM source into a windows container in read-only mode, certain tests fail. Ideally, we want all these tests to pass so that developers can mount the same source folder into multiple (windows) containers simultaneously, allowing them to build/test the same source code using various different configurations simultaneously. **Fix**: I've found that when attempting to open a file for writing on windows, if you don't have the correct permissions (trying to open a file for writing in a read-only folder), you get [Access is denied](https://support.microsoft.com/en-us/help/2623670/access-denied-or-other-errors-when-you-access-or-work-with-files-and-f). In llvm, we map this error message to a linux based error, see: https://github.com/llvm-mirror/llvm/blob/master/lib/Support/ErrorHandling.cpp This is why we see "Permission denied" in our output as opposed to the expected "No such file or directory", thus causing the tests to fail. I've changed the test locally to instead point to the root drive so that they can successfully bypass the Access is denied error when LLVM is mounted in as a read-only directory. This way, the test operate exactly the same, but we can get around the windows-complications of what error to expect in a read-only directory.

* [Fixed Point Arithmetic] Fixed Point AdditionLeonard Chan2019-01-162-12/+400
| | | | | | | | | | | | | | | | | | This patch covers addition between fixed point types and other fixed point types or integers, using the conversion rules described in 4.1.4 of N1169. Usual arithmetic rules do not apply to binary operations when one of the operands is a fixed point type, and the result of the operation must be calculated with the full precision of the operands, so we should not perform any casting to a common type. This patch does not include constant expression evaluation for addition of fixed point types. That will be addressed in another patch since I think this one is already big enough.

* [ADT] Normalize empty triple componentsPetr Hosek2018-08-081-6/+6
| | | | | | | | | | | | | | | | | LLVM triple normalization is handling "unknown" and empty components differently; for example given "x86_64-unknown-linux-gnu" and "x86_64-linux-gnu" which should be equivalent, triple normalization returns "x86_64-unknown-linux-gnu" and "x86_64--linux-gnu". autoconf's config.sub returns "x86_64-unknown-linux-gnu" for both "x86_64-linux-gnu" and "x86_64-unknown-linux-gnu". This changes the triple normalization to behave the same way, replacing empty triple components with "unknown". This addresses PR37129.

* [Fixed Point Arithmetic] Fixed Point ConstantLeonard Chan2018-08-061-1/+15
| | | | | | | | | | This patch proposes an abstract type that represents fixed point numbers, similar to APInt or APSInt that was discussed in https://reviews.llvm.org/D48456#inline-425585. This type holds a value, scale, and saturation and is meant to perform intermediate calculations on constant fixed point values. Currently this class is used as a way for handling the conversions between fixed point numbers with different sizes and radixes. For example, if I'm casting from a signed _Accum to a saturated unsigned short _Accum, I will need to check the value of the signed _Accum to see if it fits into the short _Accum which involves getting and comparing against the max/min values of the short _Accum. The FixedPointNumber class currently handles the radix shifting and extension when converting to a signed _Accum. Differential Revision: https://reviews.llvm.org/D48661 llvm-svn: 339028

| | | | | | | | | | | | | | | | as fixed point literals This addresses a bug brought up in https://bugs.llvm.org/show_bug.cgi?id=38161 where integer literals could be treated as fixed point types and throw errors related to fixed point types when the 'k' or 'r' suffix used. The fix also addresses the second issue brought up with the assertion by not treating integers as fixed point types in the first place. Integers that have suffixes 'k' and 'r' now throw the error `invalid suffix 'k/r' on integer constant`. A few more tests were also added to ensure that fixed point types, and any errors/warnings related to them, are limited to C for now. Prior discussion also at https://reviews.llvm.org/D46915.
