From: nsrikarrao <[email protected]>
On AIX (powerpc-ibm-aix*), IEEE 128-bit float is not enabled, meaning
rs6000/t-float128 and rs6000/t-linux are excluded from tmake_file.
Consequently, the _BitInt conversion routines from soft-fp/ and rs6000/
were never added to LIB2ADD on AIX targets.
This causes unresolved symbol link errors when running _BitInt testcases
in the GCC testsuite (e.g., bitint-123.c, bitint-28.c, and
bitint-ibm128-to-bitint.c)
due to missing symbols like __floatbitintdf and __fixtfbitint.
Fix this by explicitly adding the soft-fp SFmode/DFmode and IBM 128-bit
double-double TFmode _BitInt conversion routines to rs6000/t-ibm-ldouble,
and exporting the corresponding symbols in libgcc-ibm-ldouble.ver.
libgcc/ChangeLog:
* config/rs6000/t-ibm-ldouble: Add soft-fp SFmode/DFmode and
rs6000 IBM 128-bit TFmode _BitInt conversion sources to LIB2ADD.
* config/rs6000/libgcc-ibm-ldouble.ver: Export __floatbitintsf,
__fixsfbitint, __floatbitintdf, __fixdfbitint, __floatbitinttf,
and __fixtfbitint.
