D64130 introduced a bug described in the following message: https://reviews.llvm.org/D64130#1571560 The problem can happen with the following script: SECTIONS { .out : { ... FILL(0x10101010) *(.aaa) ... } The current code tries to read (0x10101010) as an expression and does not break when meets *, what results in a script parsing error. In this patch, I verify that FILL command's expression always wrapped in (). And at the same time =<fillexp> expression can be both wrapped or unwrapped. I checked it matches to bfd/gold.
