&mut self,
symbol_id: SymbolId,
section: SectionId,
data: &[u8],
align: u64
) -> u64
Append data to an existing section, and update a symbol to refer to it.
For Mach-O, this also creates a __thread_vars
entry for TLS symbols, and the
symbol will indirectly point to the added data via the __thread_vars
entry.
Returns the section offset of the data.
sourcepub fn add_symbol_bss(
&mut self,
symbol_id: SymbolId,
section: SectionId,
size: u64,

&mut self,
symbol_id: SymbolId,
section: SectionId,
size: u64,
align: u64
) -> u64
Append zero-initialized data to an existing section, and update a symbol to refer to it.
For Mach-O, this also creates a __thread_vars
entry for TLS symbols, and the
symbol will indirectly point to the added data via the __thread_vars
entry.
Returns the section offset of the data.
sourcepub fn set_symbol_data(
&mut self,
symbol_id: SymbolId,
section: SectionId,
offset: u64,
size: u64
)
pub fn set_symbol_data(
&mut self,
symbol_id: SymbolId,
section: SectionId,
offset: u64,
size: u64
)
Update a symbol to refer to the given data within a section.
For Mach-O, this also creates a __thread_vars
entry for TLS symbols, and the
symbol will indirectly point to the data via the __thread_vars
entry.
sourcepub fn symbol_section_and_offset(
&mut self,
symbol_id: SymbolId
) -> Option<(SymbolId, u64)>
pub fn symbol_section_and_offset(
&mut self,

) -> Option<(SymbolId, u64)>
Convert a symbol to a section symbol and offset.
Returns None
if the symbol does not have a section.

section: SectionId,
relocation: Relocation
) -> Result<()>
pub fn add_relocation(
&mut self,
section: SectionId,
relocation: Relocation
) -> Result<()>
