Bug ID: 30269
Summary: lld: implement --section-start, aka -Ttext etc.
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
The build for FreeBSD's boot loader components was recently reworked to use a
linker script instead of -N, but we've now encountered another issue in the
lack of -Ttext.
GNU ld documents them as:
--section-start sectionname=org
Locate a section in the output file at the absolute address given
by org. You may use this option as many times as necessary to
locate multiple sections in the command line. org must be a single
hexadecimal integer; for compatibility with other linkers, you may
omit the leading 0x usually associated with hexadecimal values.
Note: there should be no white space between sectionname, the
equals sign ("="), and org.
-Tbss org
-Tdata org
-Ttext org
Same as --section-start, with ".bss", ".data" or ".text" as the
sectionname.
However, see this note about Gold's -Ttext / -Ttext-segment:
Gold's -Ttext option is approximately the same as GNU ld's
-Ttext-segment option. This patch adds -Ttext-segment to gold as an
alias for -Ttext, so that scripts can use both linkers the same way.
This was prompted in particular by
http://gcc.gnu.org/ml/gcc-patches/2013-02/msg00699.html .
