# 3d2a9188	26-Feb-2024	PiJoules <6019989+PiJoules@users.noreply.github.com>	[clang] Fixes inf loop parsing fixed point literal (#83071) Clang was incorrectly finding the start of the exponent in a fixed point hex literal. It would unconditionally find the first `e/E/p/P` i [clang] Fixes inf loop parsing fixed point literal (#83071) Clang was incorrectly finding the start of the exponent in a fixed point hex literal. It would unconditionally find the first `e/E/p/P` in a constant regardless of if it were hex or not and parser the remaining digits as an APInt. In a debug build, this would be caught by an assertion, but in a release build, the assertion is removed and we'd end up in an infinite loop. Fixes #83050 show more ...

# a677942d	06-Aug-2018	Leonard Chan <leonardchan@google.com>	[Fixed Point Arithmetic] Fixed Point Constant This patch proposes an abstract type that represents fixed point numbers, similar to APInt or APSInt that was discussed in https://reviews.llvm.org/D484 [Fixed Point Arithmetic] Fixed Point Constant 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 show more ...
