Aaron Ballman	1ea584377e	A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the ninth batch of tests being updated (there are a significant number of other tests left to be updated).	2022-02-13 08:03:40 -05:00
Valeriy Savchenko	2a09daff0f	[analyzer] Generalize bitwise AND rules for ranges Summary: Previously the current solver started reasoning about bitwise AND expressions only when one of the operands is a constant. However, very similar logic could be applied to ranges. This commit addresses this shortcoming. Additionally, it refines how we deal with negative operands. rdar://problem/54359410 Differential Revision: https://reviews.llvm.org/D79434	2020-05-28 18:55:49 +03:00

A significant number of our tests in C accidentally use functions

without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the ninth batch of tests being updated (there are a
significant number of other tests left to be updated).

[analyzer] Generalize bitwise AND rules for ranges

Summary:
Previously the current solver started reasoning about bitwise AND
expressions only when one of the operands is a constant.  However,
very similar logic could be applied to ranges.  This commit addresses
this shortcoming.  Additionally, it refines how we deal with negative
operands.
