In next commit, we'll apply same helper pattern for base helpers
remaining.
Our new helper pattern always include helper-*-common.h, which ends up
including include/tcg/tcg.h, which contains one occurrence of
CONFIG_USER_ONLY.
Thus, common files not being duplicated between system and target
relying on helpers will fail to compile. Existing occurrences are:
- target/arm/tcg/arith_helper.c
- target/arm/tcg/crypto_helper.c
There is a single occurrence of CONFIG_USER_ONLY, for defining variable
tcg_use_softmmu. The fix seemed simple, always define it.
However, it prevents some dead code elimination which ends up triggering:
include/qemu/osdep.h:283:35: error: call to 'qemu_build_not_reached_always'
declared with attribute error: code path is reachable
283 | #define qemu_build_not_reached() qemu_build_not_reached_always()
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tcg/x86_64/tcg-target.c.inc:1907:45: note: in expansion of macro
'qemu_build_not_reached'
1907 | # define x86_guest_base (*(HostAddress *)({ qemu_build_not_reached();
NULL; }))
| ^~~~~~~~~~~~~~~~~~~~~~
tcg/x86_64/tcg-target.c.inc:1934:14: note: in expansion of macro
'x86_guest_base'
1934 | *h = x86_guest_base;
| ^~~~~~~~~~~~~~
So, roll your eyes, then rollback code, and simply duplicate the two
files concerned. We could also do a "special include trick" to prevent
pulling helper-*-common.h but it would be sad since the whole point of
the series up to here is to have something coherent using the exact same
pattern.
