Valutazione

Difficoltà: 4/5
Tempo stimato: 3-5 giorni
Idoneità per principianti: 45/100

Tipo di issue: Bug
Chiarezza: Abbastanza chiara
Stato di attività: Ferma
Stack tecnologico: c
Ambito: devtools

Direzione di ricerca

Riproduci la diagnostica della macro in libertas_cluster_base.h usando libertas_cluster_impl.c come unità di traduzione e la configurazione GCC C17 riportata. Inizia tracciando il modo in cui IntelliSense analizza attribute in questa forma di macro; il lavoro è completato quando il codice C valido non segnala più l’errore “expected a type specifier” e continua a compilare correttamente.

Scritto dal modello di indicizzazione a partire dal testo della issue.

Descrizione

embedded Feature: Configuration investigate: repro Language Service

Environment

OS and Version: Ubuntu 22/04
VS Code Version: 1.73.1
C/C++ Extension Version: 1.15.0

Bug Summary and Steps to Reproduce

Bug Summary:

Steps to reproduce:

#define BYTE_ALIGNED_TEST( __Declaration__ ) __Declaration__ __attribute__((__packed__))

BYTE_ALIGNED_TEST(
typedef struct test_struct {
	uint16_t    i;
	uint8_t      j;
}) test_struct;

Expected behavior:
The code compiles fine.

But Intellisense reports an error:
