[libc] Fix printf handling of INT_MIN width (#101729) 2024-08-02T20:45:54+00:00 Michael Jones michaelrj@google.com 2024-08-02T20:45:54+00:00 a21fc4c0a681000c23089301e8935f579517b96a Prevously, if INT_MIN was passed as a wildcard width to a printf conversion the parser would attempt to negate it to get the positive width (and set the left justify flag), but it would underflow and the width would be treated as 0. This patch corrects the issue by instead treating a width of INT_MIN as identical to -INT_MAX. Also includes docs changes to explain this behavior and adding b to the list of int conversions.

 [libc] Move printf writer to new design 2023-07-20T18:08:20+00:00 Michael Jones michaelrj@google.com 2023-06-27T20:12:15+00:00 b9f6c20876845abbe2b816d0d800b99412b5eab9 The new printf writer design focuses on optimizing the fast path. It inlines any write to a buffer or string, and by handling buffering itself can more effectively work with both internal and external file implementations. The overflow hook should allow for expansion to asprintf with minimal extra code. Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D153999

[libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory. 2023-02-07T19:45:51+00:00 Siva Chandra Reddy sivachandra@google.com 2023-02-06T07:07:23+00:00 af1315c28f9bab76d3c2e1492a3d41e7c48215f8 This part of the effort to make all test related pieces into the `test` directory. This helps is excluding test related pieces in a straight forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move the MPFR wrapper and testutils into the 'test' directory.

[libc] add snprintf 2022-05-17T20:32:59+00:00 Michael Jones michaelrj@google.com 2022-05-17T19:03:23+00:00 9f1d905f39ac7f32b1965b8062c0803955ccbd0f After adding sprintf, snprintf is simple. The functions are very similar. The tests only cover the behavior of the max length since the sprintf tests should cover the other behavior.
