minimal example to illustrate the issue
Hi there,
in an attempt to compile
http://blogs.utexas.edu/jdm4372/2013/01/17/stream-version-5-10-released/ with
clang 3.4 on a FreeBSD 10.0-stable system, the linker fails when using large
arrays and using mcodel=medium. gcc47 and higher compile and link the same
program just fine.
I've attached a minimal example "big_array.c" that fails to link when using -O0
but works with -O1 and higher.
$ clang -O0 -mcmodel=medium big_array.c -o big_array
/usr/lib/crt1.o: In function `_start':
/usr/src/lib/csu/amd64/crt1.c:(.text+0x1f): relocation truncated to fit:
R_X86_64_PC32 against symbol `environ' defined in COMMON section in
/usr/lib/crt1.o
/usr/src/lib/csu/amd64/crt1.c:(.text+0x29): relocation truncated to fit:
R_X86_64_PC32 against symbol `environ' defined in COMMON section in
/usr/lib/crt1.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Thanks & cheerio, Harry.
