› software › gnu-c-manualThe GNU C Reference Manual You can use goto statements to simulate loop statements, but we do not recommend it—it makes the program harder to read, and GCC cannot optimize it as well. You should use for, while, and do statements instead of goto statements, when possible. As an extension, GCC allows a goto statement to jump to an address specified by a void* variable.

Goto and labels in c

gcc.gnu.org › onlinedocs › gccExtended Asm (Using the GNU Compiler Collection (GCC)) The GotoLabels section in an asm goto statement contains a comma-separated list of all C labels to which the assembler code may jump. GCC assumes that asm execution falls through to the next statement (if this is not the case, consider using the __builtin_unreachable intrinsic after the asm statement). › manual › enPHP: goto - Manual The goto operator can be used to jump to another section in the program. The target point is specified by a case-sensitive label followed by a colon, and the instruction is given as goto followed by the desired target label. This is not a full unrestricted goto. The target label must be within the same file and context, meaning that you cannot ... › local-labels-in-cLocal Labels in C - GeeksforGeeks May 08, 2017 · Everybody who has programmed in C programming language must be aware about “goto” and “labels” used in C to jump within a C function. GCC provides an extension to C called “local labels”. Conventional Labels vs Local Labels Conventional labels in C have function scope. Where as local label can be scoped to a inner nested block.
