Bug ID: 22695
Summary: [SPARC64] clang 3.6 error: unknown directive ".xword"
Product: libraries
Version: 3.6
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: Sparc
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
It seems there are still some issues with the sparc integrated as:
$ cat test.c
static const long table[] = { 2, 3, 5, 7 };
long foo(int a) { return table[a]; }
// EOF
$ clang-3.6.0rc4 -target sparc64-linux-gnu -Wall -W -O2 -save-temps -c test.c
[... driver warnings about floating point, see bug 22489 ...]
test.s:24:2: error: unknown directive
.xword 2 ! 0x2
^
test.s:25:2: error: unknown directive
.xword 3 ! 0x3
^
test.s:26:2: error: unknown directive
.xword 5 ! 0x5
^
test.s:27:2: error: unknown directive
.xword 7 ! 0x7
^
Interestingly it works when *NOT* using -save-temps (which makes me wonder
what -save-temps actually does):
$ clang-3.6.0rc4 -target sparc64-linux-gnu -Wall -W -O2 -c test.c
clang: warning: unknown platform, assuming -mfloat-abi=soft
'+soft-float' is not a recognized feature for this target (ignoring feature)
