assembly - Question about ASM execution flow -


i'm not sure how interpret asm execution flow. until now, of files i've looked @ have had explicit jumps (intel x86 at&t syntax, i.e jmp or jl) labels within asm file.

my question: happens when reach end of label without explicit jump other label. execution continue next label?

example:

foo:     opcodes     ...  nextlablel:     moreopcodes     ...         

after executing opcodes under 'foo' label, assembler move onto 'nextlablel'?

thanks in advance!

the labels non existent actual code, yes, if there no branch, code execute naturally. assembler continue code, ignoring labels. labels there convenient way branching after jmp, je , likes.

if code did not have branches, still have many labels wanted. not , bad practice, illustrates idea not cause problems natural code flow.
