Bug #: 12424
Summary: compile of compiler-rt/lib/atomic.c fails on
undeclared identifier __uint128_t
Product: new-bugs
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs
AssignedTo: unassignedbugs@nondot.org
ReportedBy: nolanw_commerce@willnolan.com
CC: llvmbugs@cs.uiuc.edu
Classification: Unclassified
Straight build from svn trunk as per the instructions on the home page results
in:
/home/wnolan/clang.src/llvm/projects/compiler-rt/lib/atomic.c:149:3: error: use
of undeclared identifier '__uint128_t'
LOCK_FREE_CASES();
^
/home/wnolan/clang.src/llvm/projects/compiler-rt/lib/atomic.c:137:26: note:
expanded from macro 'LOCK_FREE_CASES'
LOCK_FREE_ACTION(__uint128_t);\
^
/home/wnolan/clang.src/llvm/projects/compiler-rt/lib/atomic.c:147:8: note:
expanded from macro 'LOCK_FREE_ACTION'
*((type*)dest) = __atomic_load((_Atomic(type)*)src, model);\
^
Seems like "configure" should have been able to nip this in the bud early in
the process, but it passed. Note that "configure" does check for {u}int64_t:
checking for int64_t... yes
checking for uint64_t... yes
As of a few months ago trunk used to build cleanly on the same host. Sorry I
can't pin down the rev #'s...
