Fix build on platforms where __USER_LABEL_PREFIX__ is not empty
|
|
|
|
On most platforms, a C language symbol and its assembly equivalent are
|
|
identical. However, on the Blackfin architecture, this isn't the case,
|
|
the corresponding C language symbol in assembly is prepended with a
|
|
"_". Blackfin therefore has __USER_LABEL_PREFIX__ defined to "_".
|
|
|
|
Cairo already has some code to cope with __USER_LABEL_PREFIX__, but
|
|
this code isn't completely correct: it prepends both assembly symbols
|
|
and C symbols with __USER_LABEL_PREFIX__, which cannot work.
|
|
|
|
This patch fixes that by using the existing slim_hidden_asmname() to
|
|
define assembly symbols, and introduce a new slim_hidden_realname()
|
|
for C symbols.
