Bug ID: 21095
Summary: Wrong handling of minimal long long integer
(-9223372036854775808ll) literal
Product: clang
Version: unspecified
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: oliora at gmail.com
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
According to specs, the minimal possible signed long long integer on modern
MacBook (Intel Core i7 CPU) is -9223372036854775808. But when I specify it (as
-9223372036854775808ll) I got warning "Integer constant is larger than the
largest signed integer type" and integer is converted into usnigned long long
with value 9223372036854775808.
