Bug ID: 28926
Summary: support VERSION in linker script
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
Classification: Unclassified
Symbol version information can be provided via the --version-script command
line option, or can be embedded into a VERSION block in a linker script:
VERSION { version-script-commands }
FreeBSD uses this for the Linux ABI vDSO support, presumably from the same use
in the Linux kernel.
Reference: https://www.sourceware.org/binutils/docs/ld/VERSION.html#VERSION
Example:
VERSION
{
LINUX_2.6 {
global:
time;
__vdso_time;
gettimeofday;
__vdso_gettimeofday;
getcpu;
__vdso_getcpu;
clock_gettime;
__vdso_clock_gettime;
linux_rt_sigcode;
linux_platform;
local: *;
};
}
