From 7c1395a7e4d3d994a986ef2bc5457ba3f4aaec22 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Fri, 26 Dec 2014 16:18:40 -0500 Subject: [PATCH] tilegx32: avoid a a -Werror warning from unwinding The _Unwind_GetCFA() routine returns a 64-bit value, which we interpret as a pointer. Add an intermediate cast to long so that in ILP32 mode we don't get a warning about casting a wrong-sized integer to a pointer. --- ChangeLog | 5 +++++ sysdeps/tile/jmpbuf-unwind.h | 2 +- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/ChangeLog b/ChangeLog index f7bfe91..3b01ed88 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2014-12-26 Chris Metcalf + + * sysdeps/tile/jmpbuf-unwind.h (_JMPBUF_CFA_UNWINDS_ADJ): Cast to + long before casting to pointer to avoid a cast warning. + 2014-12-23 Chris Metcalf * sysdeps/tile/tilegx/Implies: New file. diff --git a/sysdeps/tile/jmpbuf-unwind.h b/sysdeps/tile/jmpbuf-unwind.h index 3925e90..ec0be21 100644 --- a/sysdeps/tile/jmpbuf-unwind.h +++ b/sysdeps/tile/jmpbuf-unwind.h @@ -29,7 +29,7 @@ ((void *) (address) < (void *) demangle ((jmpbuf)[JB_SP])) #define _JMPBUF_CFA_UNWINDS_ADJ(_jmpbuf, _context, _adj) \ - _JMPBUF_UNWINDS_ADJ (_jmpbuf, (void *) _Unwind_GetCFA (_context), _adj) + _JMPBUF_UNWINDS_ADJ (_jmpbuf, (void *) (long) _Unwind_GetCFA (_context), _adj) static inline uintptr_t __attribute__ ((unused)) _jmpbuf_sp (__jmp_buf regs) -- 2.7.4
