1. Remove _dl_runtime_resolve_shstk and _dl_runtime_profile_shstk. 2. Move CET offsets from x86 cpu-features-offsets.sym to x86-64 features-offsets.sym. 3. Rename x86 cet-control.h to x86-64 feature-control.h since it is only for x86-64 and also used for PLT rewrite. 4. Add x86-64 ldsodefs.h to include feature-control.h. 5. Change TUNABLE_CALLBACK (set_plt_rewrite) to x86-64 only. 6. Move x86 dl-procruntime.c to x86-64. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

All the #ifdefs in the definitions are quite irritating but

necessary if we want to avoid duplicating the information. There

are three different modes:

|
- PROCINFO_DECL is defined. This means we are only interested in
|
|
declarations.
|
|
|
|
- PROCINFO_DECL is not defined:
|
|
|
|
+ if SHARED is defined the file is included in an array
|
|
initializer. The .element = { ... } syntax is needed.
|
|
|
|
+ if SHARED is not defined a normal array initialization is
|
|
needed.
