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.
This patch puts absolute jump table in read only relocation section if
the
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 Joseph,
here is the (unfinished) patch to support
mixing of labels in C2X.
I preserved existing tests by adding
"-std=c17 -pedantic-error"
So far, I haven't figured out how
to fix the OpenMP related warning
in 'gcc.dg/gomp/barrier-2.c'.
Best,
Martin

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.
Fixed by streaming
