Bug ID: 28720
Summary: lld does not accept dot assignment in an output
section
Product: lld
Version: unspecified
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P
Component: ELF
Assignee: unassignedb...@nondot.org
Reporter: ema...@freebsd.org
CC: llvm-bugs@lists.llvm.org
Blocks: 23214
Classification: Unclassified
FreeBSD/amd64's kernel ldscript assigns . in an output section like so:
6 SECTIONS
7 {
...
146 .bss :
147 {
148 *(.dynbss)
149 *(.bss .bss.* .gnu.linkonce.b.*)
150 *(COMMON)
151 /* Align here to ensure that the .bss section occupies space up to
152 _end. Align after .bss to ensure correct alignment even if the
153 .bss section disappears because there are no input sections.
154 FIXME: Why do we need it? When there is no .bss section, we don't
155 pad the .data section. */
156 . = ALIGN(. != 0 ? 64 / 8 : 1);
157 }
lld's parser does not accept this:
line 156: unknown command .
. = ALIGN(. != 0 ? 64 / 8 : 1);
^
For FreeBSD's uses we could just move the assignment out of that section but
perhaps this is more commonly needed?
