Bug ID: 109257
Summary: `-masm=intel` generates weird syntax for indirect
jumps
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: lh_mouse at 126 dot com
Target Milestone: ---
https://gcc.godbolt.org/z/Tc8v5qfv1
a proper tail call:
```
extern int (*foo)(int, int);
int ptc_to_foo(int a, int b) { return foo(a, b); }
```
GCC compiles it to this:
```
ptc_to_foo:
jmp [QWORD PTR foo[rip]]
```
The outer pair of brackets are superfluous.
The `foo[rip]` part is also invalid but it's a common issue for all addressing
operands for x86_64, not specifically about jmp.
