On ARM, we want to make sure that GHC uses the gold linker.
|
|
|
b032d48 |
|
|
|
b032d48 |
In order to achieve that, we need to get `-fuse-ld=gold` into
|
|
|
b032d48 |
SettingsCCompilerLinkFlags in the settings.
|
|
|
b032d48 |
|
|
|
b032d48 |
This field is filled with only CONF_GCC_LINKER_OPTS_STAGE2. So we want that
|
|
|
b032d48 |
flag to show up there.
|
|
|
b032d48 |
|
|
|
b032d48 |
But this variable is used in a few other cases (LDFLAGS, options to hsc2hs)
|
|
|
b032d48 |
where -fuse-ld=gold caused problems.
|
|
|
b032d48 |
(These problems were not investigated. Maybe _they_ could be solved?)
|
|
|
b032d48 |
|
|
|
b032d48 |
So as a work-around we remove any other use of CONF_GCC_LINKER_OPTS_STAGE2.
