* elf32-s390: Major rework that introduces all recent changes to the s390 backends. Get a closer match to elf32-i386. (elf_s390_relocate_section): Make use of dynamic section short-cuts. Localise vars, and delay setting. Better error reporting, replace BFD_ASSERT with abort. Check ELF_LINK_HASH_DEF_DYNAMIC to see if a symbol is not defined in the regular object file and tread the weak definition as the normal one. Don't discard relocs for undefweak or undefined symbols and check !DEF_REGULAR as well as DEF_DYNAMIC in test for avoided copy relocs. Reinstate fudge for unresolved relocs in debugging sections. (elf32_s390_adjust_dynamic_symbol): Handle nocopyreloc. Don't do copy reloc processing for weakdefs. Remove redundant casts and aborts. Delay setting of vars until needed. Move creation of dynamic symbols and allocation of .plt and .rela.plt to allocate_dynrelocs. Replace BFD_ASSERT with abort. Discard .plt entries for everything with plt.refcount <= 0. (elf_s390_check_relocs): Don't allocate space for dynamic relocs, .got or .relgot here but do it in allocate_dynrelocs. Reference count possible .plt and .got entries. Don't test input section SEC_READONLY here to try to avoid copy relocs, and keep dyn_relocs regardless of ELF_LINK_NON_GOT_REF. Don't set DF_TEXTREL here. Delay setting of variables until needed. Remove separate switch stmt for creating .got section. Initialise local_got_refcounts to 0. Cache pointer to "sreloc" section in elf_section_data. Tweak condition under which .got created. Report files with bad relocation section names. (elf_s390_finish_dynamic_symbol): Don't copy relocs for symbols that have been forced local. Use same test to decide if we can use a relative reloc for got as elf_s390_relocate_section. Expand SHN_UNDEF comment. Move expressions out of function calls. Replace BFD_ASSERT with abort. (elf_s390_finish_dynamic_sections): Migrate common code out of switch statement. Replace BFD_ASSERT with abort. (elf_s390_size_dynamic_sections): Call readonly_dynrelocs. Rename "i" to "ibfd". Allocate space for local dyn relocs. Use DF_TEXTREL flag instead of looking up section names for DT_TEXTREL. Replace BFD_ASSERT with abort. Zero out the dynamic allocated content space. Add a comment to remind us that one day this ought to be fixed. (struct elf_s390_link_hash_entry): Rename "root" to "elf". (struct elf_s390_link_hash_table): Likewise. (elf_s390_link_hash_newfunc): Rename to link_hash_newfunc and get rid of unnecessary casts. (struct elf_s390_dyn_relocs): Add "sec", and "pc_count" fields. Remove "section" field.

The loader then gets:
24(15) = Pointer to the structure describing the object.
28(15) = Offset in symbol table
2001-02-10 01:58:38 +01:00
The loader must then find the module where the function is
and insert the address in the GOT.
Note: 390 can only address +- 64 K relative.
We check if offset > 65536, then make a relative branch -64xxx
back to a previous defined branch
PLT1: BASR 1,0 # 2 bytes
L 1,22(1) # 4 bytes Load offset in GOT in r 1
L 1,(1,12) # 4 bytes Load address from GOT in r1
BCR 15,1 # 2 bytes Jump to address
RET1: BASR 1,0 # 2 bytes Return from GOT 1st time
L 1,14(1) # 4 bytes Load offset in symol table in r1
BRC 15,-x # 4 bytes Jump to start of PLT
.word 0 # 2 bytes filler
.long ? # 4 bytes offset in GOT
.long ? # 4 bytes offset into symbol table
This was the general case. There are two additional, optimizes PLT
definitions. One for GOT offsets < 4096 and one for GOT offsets < 32768.
First the one for GOT offsets < 4096:
PLT1: L 1,<offset>(12) # 4 bytes Load address from GOT in R1
BCR 15,1 # 2 bytes Jump to address
.word 0,0,0 # 6 bytes filler
RET1: BASR 1,0 # 2 bytes Return from GOT 1st time
L 1,14(1) # 4 bytes Load offset in symbol table in r1
BRC 15,-x # 4 bytes Jump to start of PLT
.word 0,0,0 # 6 bytes filler
.long ? # 4 bytes offset into symbol table
Second the one for GOT offsets < 32768:
PLT1: LHI 1,<offset> # 4 bytes Load offset in GOT to r1
L 1,(1,12) # 4 bytes Load address from GOT to r1
BCR 15,1 # 2 bytes Jump to address
.word 0 # 2 bytes filler
RET1: BASR 1,0 # 2 bytes Return from GOT 1st time
L 1,14(1) # 4 bytes Load offset in symbol table in r1
BRC 15,-x # 4 bytes Jump to start of PLT
.word 0,0,0 # 6 bytes filler
.long ? # 4 bytes offset into symbol table
Total = 32 bytes per PLT entry
The code for static build PLT entries looks like this:
PLT1: BASR 1,0 # 2 bytes
L 1,22(1) # 4 bytes Load address of GOT entry
L 1,0(0,1) # 4 bytes Load address from GOT in r1
BCR 15,1 # 2 bytes Jump to address
RET1: BASR 1,0 # 2 bytes Return from GOT 1st time
L 1,14(1) # 4 bytes Load offset in symbol table in r1
BRC 15,-x # 4 bytes Jump to start of PLT
.word 0 # 2 bytes filler
.long ? # 4 bytes address of GOT entry
.long ? # 4 bytes offset into symbol table */

against a global symbol, or a non PC relative reloc
against a local symbol, then we need to copy the reloc
into the shared library. However, if we are linking with
-Bsymbolic, we do not need to copy a reloc against a
global symbol which is defined in an object we are
including in the link (i.e., DEF_REGULAR is set). At
this point we have not seen all the input files, so it is
possible that DEF_REGULAR is not set now but will be set
later (it is never cleared). In case of a weak definition,
DEF_REGULAR may be cleared later by a strong definition in
a shared library. We account for that possibility below by
storing information in the relocs_copied field of the hash
table entry. A similar situation occurs when creating
shared libraries and symbol visibility changes render the
symbol local.
If on the other hand, we are creating an executable, we
may need to keep relocations for symbols satisfied by a
dynamic library if we manage to avoid copy relocs for the
symbol. */

Localise vars, and delay setting. Better error reporting, replace BFD_ASSERT with abort. Check ELF_LINK_HASH_DEF_DYNAMIC to see if a symbol is not defined in the regular object file and tread the weak definition as the normal one. Don't discard relocs for undefweak or undefined symbols and check !DEF_REGULAR as well as DEF_DYNAMIC in test for avoided copy relocs. Reinstate fudge for unresolved relocs in debugging sections. (elf32_s390_adjust_dynamic_symbol): Handle nocopyreloc. Don't do copy reloc processing for weakdefs. Remove redundant casts and aborts. Delay setting of vars until needed. Move creation of dynamic symbols and allocation of .plt and .rela.plt to allocate_dynrelocs. Replace BFD_ASSERT with abort. Discard .plt entries for everything with plt.refcount <= 0. (elf_s390_check_relocs): Don't allocate space for dynamic relocs, .got or .relgot here but do it in allocate_dynrelocs. Reference count possible .plt and .got entries. Don't test input section SEC_READONLY here to try to avoid copy relocs, and keep dyn_relocs regardless of ELF_LINK_NON_GOT_REF. Don't set DF_TEXTREL here. Delay setting of variables until needed. Remove separate switch stmt for creating .got section. Initialise local_got_refcounts to 0. Cache pointer to "sreloc" section in elf_section_data. Tweak condition under which .got created. Report files with bad relocation section names. (elf_s390_finish_dynamic_symbol): Don't copy relocs for symbols that have been forced local.

* elf32-s390: Major rework that introduces all recent changes to the s390 backends. Get a closer match to elf32-i386. (elf_s390_relocate_section): Make use of dynamic section short-cuts. Localise vars, and delay setting. Better error reporting, replace BFD_ASSERT with abort. Check ELF_LINK_HASH_DEF_DYNAMIC to see if a symbol is not defined in the regular object file and tread the weak definition as the normal one. Don't discard relocs for undefweak or undefined symbols and check !DEF_REGULAR as well as DEF_DYNAMIC in test for avoided copy relocs. Reinstate fudge for unresolved relocs in debugging sections. (elf32_s390_adjust_dynamic_symbol): Handle nocopyreloc. Don't do copy reloc processing for weakdefs. Remove redundant casts and aborts. Delay setting of vars until needed. Move creation of dynamic symbols and allocation of .plt and .rela.plt to allocate_dynrelocs. Replace BFD_ASSERT with abort. Discard .plt entries for everything with plt.refcount <= 0. (elf_s390_check_relocs): Don't allocate space for dynamic relocs, .got or .relgot here but do it in allocate_dynrelocs. Reference count possible .plt and .got entries. Don't test input section SEC_READONLY here to try to avoid copy relocs, and keep dyn_relocs regardless of ELF_LINK_NON_GOT_REF. Don't set DF_TEXTREL here. Delay setting of variables until needed. Remove separate switch stmt for creating .got section. Initialise local_got_refcounts to 0. Cache pointer to "sreloc" section in elf_section_data. Tweak condition under which .got created. Report files with bad relocation section names. (elf_s390_finish_dynamic_symbol): Don't copy relocs for symbols that have been forced local. Use same test to decide if we can use a relative reloc for got as elf_s390_relocate_section. Expand SHN_UNDEF comment. Move expressions out of function calls. Replace BFD_ASSERT with abort. (elf_s390_finish_dynamic_sections): Migrate common code out of switch statement. Replace BFD_ASSERT with abort. (elf_s390_size_dynamic_sections): Call readonly_dynrelocs. Rename "i" to "ibfd". Allocate space for local dyn relocs. Use DF_TEXTREL flag instead of looking up section names for DT_TEXTREL. Replace BFD_ASSERT with abort. Zero out the dynamic allocated content space. Add a comment to remind us that one day this ought to be fixed. (struct elf_s390_link_hash_entry): Rename "root" to "elf". (struct elf_s390_link_hash_table): Likewise. (elf_s390_link_hash_newfunc): Rename to link_hash_newfunc and get rid of unnecessary casts. (struct elf_s390_dyn_relocs): Add "sec", and "pc_count" fields. Remove "section" field. (elf_s390_gc_sweep_hook): Sweep dyn_relocs and local_dynrel. Reference count possible .plt entries. Don't deallocate .got and .relgot space here.
