Hi,
Jump tables are put into text or rodata section originally. On some
platforms, it gains the performance benefit from absolute address jump
tables. So I want to let absolute address jump table be relocatable.

hi, one of my work need to instrument a memset function (since the memset are
inserted after pass_expand). I find inserting a function before memset directly
will lead to segment fault. I think the inserted funtion destroy memset funtion
arguments. I put the inserted funtion after memset, run

I see. So this is not considered a bug then?
P.S. it seems that -faligned-new=8 can be used as a workaround in this case,
even in pre-c++17 modes, so the issue doesn't look that bad in the end.

Patch for MVBITS:
https://gcc.gnu.org/pipermail/fortran/2020-September/055071.html
Dear all,
finally here comes the second part of runtime checks for the bit
manipulation intrinsics, this time MVBITS. This turned out to be
more elaborate than the treatment of simple function calls.
I chose the path to inline expand MVBITS, which enables additional
optimization opportunities

Hi!
The large patch for opts_set saving/restoring doesn't seem to be desirable
for backporting (it can be backported and I've even tested it in gcc 10,
but it is too large), so this patch instead provides a target only fix.
As opts_set can't be trusted, it uses TargetVariables to record whether

Hi!
When working on the previous patch, I've noticed that all cl_optimization
fields appart from strings are streamed with bp_pack_value (..., 64); so we
waste quite a lot of space, given that many of the options are just booleans
or char options and there are 450-ish of them.
