Posted a qemu patch last Friday
https://lists.nongnu.org/archive/html/qemu-devel/2019-11/msg02480.html
Some sections need to be placed first, e.g. .interp and some .note*. Core
dumpers give priority to first few pages. So the option may end up placing R
sections in both sides of RX. The code size inefficiency will also lower its
utility. R and RW on both sides of RX makes it less likely to cause relocation
overflows for large executables/shared objects.
Another point worth mentioning: -Ttext and -Ttext-segment are different in GNU
ld, but both lld and gold implement -Ttext and -Ttext-segment as aliases.
gold sets the segment address (GNU ld -Ttext-segment behavior) while lld sets
the .text address (GNU ld -Ttext behavior). We probably should remove
-Ttext-segment to avoid confusion, if we don't intend to support it (it is very
old-fashioned).
