Bug ID: 15666
Summary: clang does not know Red Hat Linux ARM triplets
armv7hl-redhat-linux and armv5tel-redhat-linux
Product: clang
Version: 3.2
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Driver
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Clang on Fedora ARM does not work well because clang does not
recognize the Fedora ARM triplets and fallback to software floating point,
causing build failures like this:
clang: warning: unknown platform, assuming -mfloat-abi=soft

Earlier I tried a simple naive patch like:
--- llvm-3.2.src/tools/clang/lib/Driver/ToolChains.cpp~ 2012-12-17
00:59:27.000000000 +0900
+++ llvm-3.2.src/tools/clang/lib/Driver/ToolChains.cpp 2013-02-12
19:18:00.755164292 +0900
@@ -1054,10 +1054,12 @@
static const char *const ARMLibDirs[] = { "/lib" };
static const char *const ARMTriples[] = {

+ "armv5tel-redhat-linux",
};
static const char *const ARMHFTriples[] = {
"arm-linux-gnueabihf",

};
but it was not sufficient - maybe fixes are also needed to on the llvm side,
perhaps?
(Similarly ppc64-redhat-linux is also not supported.)
