BFD whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

|
|
Return @code{TRUE} if the full section contents is retrieved
|
2014-12-02 00:43:46 +08:00
|
|
|
successfully. If the section has no contents then this function
|
|
|

BFD whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.
