Bug ID: 22267
Summary: ld.bfd does not accept "foo = ~0xFF" in linker script
but accepts "foo = ~ 0xFF"
Product: binutils
Version: 2.30 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: georgerim at gmail dot com
Target Milestone: ---
Following linkerscript triggers an error when using
"GNU ld (GNU Binutils) 2.29.51.20171006":
SECTIONS { . = 0x10000; foo = ~0xFF; }
"test.script:3: undefined symbol `~0xFF' referenced in expression"
Though when I insert space between `~` and `0xFF`, ld.bfd parses script fine:
SECTIONS { . = 0x10000; foo = ~ 0xFF; }
It is not clear what is intentional behavior, as it not documented I think, but
ld.bfd does not require space in following assignment: "foo = !0xFF".
FWIW gold also does not have this "issue", I'll open bug for it too just in
case it has unwanted relaxed behavior.
