Summary: Typo in x86 built-in function list
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: web
Assignee: unassigned at gcc dot gnu.org

says:
```
The following built-in functions are available when -mlzcnt is used. All of
them generate the machine instruction that is part of the name.
unsigned short __builtin_ia32_lzcnt_16(unsigned short);
unsigned int __builtin_ia32_lzcnt_u32(unsigned int);
unsigned long long __builtin_ia32_lzcnt_u64 (unsigned long long);
```
The first function `__builtin_ia32_lzcnt_16()` doesn't exist. It is
`__builtin_ia32_lzcnt_u16()` that exists.
