 GROUP : {
    .ivor_branch_table (VLECODE) LOAD (ADDR(exception_handlers)) : {}
    .__exception_handlers  (VLECODE) LOAD (_e_ivor_branch_table) : {}
 } > exception_handlers

Where is the section ".ivor_branch_table" defined?

Where is the symbol "_e_ivor_branch_table" defined?

How to understand the meaning of structure above?

Hi,

section .ivor_branch_table is is defined by this line:

.ivor_branch_table (VLECODE) LOAD (ADDR(exception_handlers)) : {}

Symbol _e_ivor_branch_table is automatically generated by linker. It is the address of the end of the section .ivor_branch_table.

Meaning of the group is following:

1) create section .ivor_branch_table and load it to the address of exceptions_handlers defined in memory location.

2) create section .__exception_handlers and load it to address defined by _e_ivor_branch_table symbol (below the section .ivor_branch_table).

If you have any other questions, please feel free to write me back.

Regards,

Martin
