/* Section name for stubs is the associated section name plus this

string. */
|
to hold the stubs for that group. The name of the stub section is based
|
#define STUB_SUFFIX ".stub"
|
upon the name of another section within that group with the suffix below
|
|
applied.
|
|
|
|
PR 13049: STUB_SUFFIX used to be ".stub", but this allowed the user to
|
|
create what appeared to be a linker stub section when it actually
|
|
contained user code/data. For example, consider this fragment:
|
|
|
|
const char * stubborn_problems[] = { "np" };
|
|
|
|
If this is compiled with "-fPIC -fdata-sections" then gcc produces a
|
|
section called:
|
|
|
|
.data.rel.local.stubborn_problems
|
|
|
|
This then causes problems in arm32_arm_build_stubs() as it triggers:
|
|
|
|
// Ignore non-stub sections.
|
|
if (!strstr (stub_sec->name, STUB_SUFFIX))
|
|
continue;
|
|
|
|
And so the section would be ignored instead of being processed. Hence
|
|
the change in definition of STUB_SUFFIX to a name that cannot be a valid
|
|
C identifier. */
