#include "hashtab.h"
/* This structure is used to hold information about one GOT entry.
- There are three types of entry:
-
- (1) absolute addresses
- (abfd == NULL)
- (2) SYMBOL + OFFSET addresses, where SYMBOL is local to an input bfd
- (abfd != NULL, symndx >= 0)
- (3) SYMBOL addresses, where SYMBOL is not local to an input bfd
- (abfd != NULL, symndx == -1)
-
- Type (3) entries are treated differently for different types of GOT.
- In the "master" GOT -- i.e. the one that describes every GOT
- reference needed in the link -- the mips_got_entry is keyed on both
- the symbol and the input bfd that references it. If it turns out
- that we need multiple GOTs, we can then use this information to
- create separate GOTs for each input bfd.
-
- However, we want each of these separate GOTs to have at most one
- entry for a given symbol, so their type (3) entries are keyed only
- on the symbol. The input bfd given by the "abfd" field is somewhat
- arbitrary in this case.
-
- This means that when there are multiple GOTs, each GOT has a unique
- mips_got_entry for every symbol within it. We can therefore use the
- mips_got_entry fields (tls_type and gotidx) to track the symbol's
- GOT index.
-
- However, if it turns out that we need only a single GOT, we continue
- to use the master GOT to describe it. There may therefore be several
- mips_got_entries for the same symbol, each with a different input bfd.
- We want to make sure that each symbol gets a unique GOT entry, so when
- there's a single GOT, we use the symbol's hash entry, not the
- mips_got_entry fields, to track a symbol's GOT index. */
+ There are four types of entry:
+
+ (1) an absolute address
+ requires: abfd == NULL
+ fields: d.address
+
+ (2) a SYMBOL + OFFSET address, where SYMBOL is local to an input bfd
+ requires: abfd != NULL, symndx >= 0, tls_type != GOT_TLS_LDM
+ fields: abfd, symndx, d.addend, tls_type
+
+ (3) a SYMBOL address, where SYMBOL is not local to an input bfd
+ requires: abfd != NULL, symndx == -1
+ fields: d.h, tls_type
+
+ (4) a TLS LDM slot
+ requires: abfd != NULL, symndx == 0, tls_type == GOT_TLS_LDM
