Bad instruction on x86_64 build on OS X with DTRACE_PROBE
I was looking at mod_trace (http://prefetch.net/projects/apache_modtrace/index.html
) and playing with getting it to compile on OS X.
When building for x86_64 with -arch x86_64 we get bad instructions
generated:
gcc -o foo -arch x86_64 foo.c
/var/folders/rV/rV1x2DafFr0R6tGG+1bbk++++TM/-Tmp-//ccnykQ1o.s:11:bad
register name `%%esi)''
Using gcc -S I can definitely see we are not generating correct code:
LCFI1:
__dtrace_probe$6_foo___probe__noargs:
nop
leal 0(%%esi), %%esi
Building with -arch i386 works, DTRACE_PROBE1, etc also seem to work
on OS X based...
