Subject: [PATCH 21/23] libctf: exclude always-emitted Solaris symbols from the
|
|
symtypetab
|
|
|
|
If we're skipping _BEGIN_ and _END_ we should certainly skip all the other
|
|
ABI-required always-emitted symbols given in ld/emultempl/solaris2*em as
|
|
well. (This fixes a couple of diagnostics tests, but that's just because
|
|
the tests are quite sensitive to CTF section sizes, and introducing any
|
|
symtypetab entries for those tests perturbs those.)
|
|
|
|
Some of these are usually STT_NOTYPE, but not always: if programs already
|
|
emitted the symbol they might end up with any type, in particular
|
|
STT_OBJECT, and appear in the symtypetabs.
|
|
|
|
[nca: added commit log, added more symbols]

|
|
more always-emitted Solaris symbols.
