[Bug binutils/13503] New: [avr] Support RELOCs to represent a byte
http://sourceware.org/bugzilla/show_bug.cgi?id=13503 Bug #: 13503 Summary: [avr] Support RELOCs to represent a byte Product: binutils Version: 2.23 (HEAD) Status: NEW Severity: normal Priority: P2 Component: binutils AssignedTo: unassig...@sourceware.org ReportedBy: g...@gcc.gnu.org CC: eric.wedding...@atmel.com Classification: Unclassified Target: avr Suppose the following C code from avr-gcc 4.7: extern const __pgmx char foo; const __pgmx void * pointer = foo; Notice that __pgmx is not a macro but a new built-in keyword for a named address space that can hold 24-bit pointers. The code from above tries to assembler the address of foo. However, there is *no* way to do that in binutils because the recprective RELOCs like hh8 are not allowed in places they are needed: .globalpointer .data .typepointer, @object .sizepointer, 3 pointer: .wordfoo .warningassembling 24-bit address needs binutils extension for hh8(foo) .byte0 ; hh8(foo) avr-gcc emits a 0 to work around that but the code of not correct as the high part of the address will always be 0. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

[Bug gold/13505] New: apply_relocation always use 64bit little endian relocation
http://sourceware.org/bugzilla/show_bug.cgi?id=13505
Bug #: 13505
Summary: apply_relocation always use 64bit little endian
relocation
Product: binutils
Version: 2.23 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gold
AssignedTo: i...@airs.com
ReportedBy: hjl.to...@gmail.com
CC: ccout...@google.com
Classification: Unclassified
There are
templateint size, bool big_endian, typename Target_type,
typename Relocate
void
apply_relocation(const Relocate_infosize, big_endian* relinfo,
Target_type* target,
typename elfcpp::Elf_typessize::Elf_Addr r_offset,
unsigned int r_type,
typename elfcpp::Elf_typessize::Elf_Swxword r_addend,
const Symbol* gsym,
unsigned char* view,
typename elfcpp::Elf_typessize::Elf_Addr address,
section_size_type view_size)
{
// Construct the ELF relocation in a temporary buffer.
const int reloc_size = elfcpp::Elf_sizes64::rela_size;
unsigned char relbuf[reloc_size];
elfcpp::Rela64, false rel(relbuf);
elfcpp::Rela_write64, false orel(relbuf);
orel.put_r_offset(r_offset);
orel.put_r_info(elfcpp::elf_r_info64(0, r_type));
orel.put_r_addend(r_addend);
...
in target-reloc.h. It always uses Rela64, false even for 32bit or big
endian target.
