enable expensive run-time checks. With LIST, enable
only specific categories of checks. Categories are:
yes,no,all,none,release. Flags are:
- assert,df,fold,gc,gcac,gimple,misc,
+ assert,df,extra,fold,gc,gcac,gimple,misc,
rtlflag,rtl,runtime,tree,valgrind,types
--enable-coverage[=LEVEL]
enable compiler's code coverage collection. Use to
package
--enable-tls enable or disable generation of tls code overriding
the assembler check for tls support
+ --enable-vtable-verify enable vtable verification feature
--enable-objc-gc enable the use of Boehm's garbage collector with the
GNU Objective-C runtime
--disable-shared don't provide a shared libgcc
