Bug ID: 382256
Summary: gz compiler flag test doesn't work for gold
Product: valgrind
Version: 3.12.0
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: r...@burtonini.com
Target Milestone: ---
The compiler flag tests for -gz=zlib and -gz=zlib-gnu currently use
AC_COMPILE_IFELSE, but as these are basically linker flags it appears this is
just checking that the frontend supports them.
For example if binutils is configured so that gold is the default linker the
tests pass:
checking if gcc accepts -g -gz=zlib... yes
checking if gcc accepts -g -gz=zlib-gnu... yes
but the actual use of them fails:
| x86_64-poky-linux-gcc: error: -gz=zlib is not supported in this configuration
Changing AC_COMPILE_IFELSE to AC_LINK_IFELSE means that configure detects that
-gz=zlib doesn't work but zlib-gnu does, and the build works.
