In GNU ld, -Ttext sets the address of the .text section and -Ttext-segment sets the address of the text segment (RX).
gold only supports the -Ttext-segment semantic and treats -Ttext as an alias for -Ttext-segment.
lld only supports the -Ttext semantic and treats -Ttext-segment as an
alias for -Ttext. The text segment will be assigned to an address less
than the specified -Ttext-segment value.
This patch drops the -Ttext-segment alias.
The text segment is traditionally the first segment. Users who specify
-Ttext-segment may actually want to specify --image-base, the lld way to
express this. Unfortunately currently this is supported by GNU ld's
COFF port but not by its ELF port. gold does not support this option.
With -z separate-code, the behavior of GNU ld -Ttext-segment is weird (see https://sourceware.org/bugzilla/show_bug.cgi?id=25207)
rL289827 introduced the alias for linking qemu's non-pie user mode
binaries. As explained previously, this actually assigns the text
segment to an address less than 0x60000000. I feel that a better fix is
on the qemu side:
