[lld][ELF] lld reports error when region name in Memory Command contains symbol - #77286

Open Yunzezhu94 opened 9 months ago

Yunzezhu94 commented 9 months ago

When link with linker script like:

MEMORY
{
    A-XXXX : ORIGIN = 0x0        , LENGTH = 0x20000
    B-YYYY : ORIGIN = 0x200000 , LENGTH = 0x40000
    C-ZZZZ : ORIGIN = 0x400000 , LENGTH = 0x80000
}

lld reports error: : expected, but got - while gnu ld will not report error with same linker script. This is because when processing tokens lld treats string as Expr and split in function tokenizeExpr, so symbol - , rather than symbol : is regard as end of region name.
