Description
Environment
- OS and Version: Windows 10 Pro 22H2
- VS Code Version: 1.89.1
- C/C++ Extension Version: 1.20.5
Bug Summary and Steps to Reproduce
Bug Summary:
By hitting ctrl+space IntelliSense is not able to provide any suggestions for struct members as shown in the attached screenshots.
The same thing happens also with struct pointer, dereferenced by ->
Steps to reproduce:
- Create a function-like macro :
#define SET_BIT(REG, BIT) ((REG) |= (BIT))
- Declare the struct:
struct
{
int member1;
int member2;
} Example;
- Create the alias for this struct:
#define STRUCT_DEF Example
- Use new alias within a macro:
SET_BIT(STRUCT_DEF.member1, 1 << 0);
Expected behavior:
The alias STRUCT_DEF should be expanded after . (or -> if it's a pointer) operator
