#1533: FFI: exporting the same thing multiple times fails: error: redefinition
of
‘stginit_export_ShouldCompile_zdfdiv’
-----------------------------+----------------------------------------------
Reporter: igloo | Owner:
Type: bug | Status: new
Priority: high | Milestone: 6.8
Component: Compiler (FFI) | Version: 6.6.1
Severity: normal | Keywords:
Difficulty: Unknown | Os: Unknown
Testcase: cc013 | Architecture: Unknown
-----------------------------+----------------------------------------------
If we foreign export the same thing multiple times, e.g.:
{{{
foreign export ccall "addByte" (+) :: Int8 -> Int8 -> Int8
foreign export ccall "addInt" (+) :: Int16 -> Int16 -> Int16
foreign export ccall "addLong" (+) :: Int32 -> Int32 -> Int32
}}}
then compilation fails due to redefinition of
stginit_export_ShouldCompile_zdfzp.
In the _stub.c we generate
{{{
static void stginit_export_ShouldCompile_zdfzp()
__attribute__((constructor));
static void stginit_export_ShouldCompile_zdfzp()
{getStablePtr((StgPtr) &ShouldCompile_zdfzp_closure);}
}}}
n times.
It looks like the fix is simply to only generate it once; we just need to
rejig the code so that that happens.
Test is cc013.
