Here you go (DTRACE_CLASSLOAD_PROBE(loaded, k, shared_class);
preprocessed):
{ char* data = __null; int len = 0; Symbol* name = (k)->name(); if (name != __null) { data = (char*)name->bytes(); len = name->utf8_length(); } do { __asm__ __volatile__ ("990: nop" "\n" ".pushsection .note.stapsdt" "," "\"\"" "," "\"note\"" "\n" ".balign 4" "\n" ".4byte 992f-991f" "," "994f-993f" "," "3" "\n" "991: .asciz \"stapsdt\"" "\n" "992: .balign 4" "\n" "993: .8byte 990b" "\n" ".8byte _.stapsdt.base" "\n" ".8byte 0" "\n" ".asciz \"hotspot\"" "\n" ".asciz \"class__loaded\"" "\n" ".asciz \"%n[_SDT_S1]@%[_SDT_A1] %n[_SDT_S2]@%[_SDT_A2] %n[_SDT_S3]@%[_SDT_A3] %n[_SDT_S4]@%[_SDT_A4]\"" "\n" "994: .balign 4" "\n" ".popsection" "\n" :: [_SDT_S1] "n" (((!(__builtin_classify_type (data) == 14 || __builtin_classify_type (data) == 5) && __sdt_type<__typeof (data)>::__sdt_signed) ? 1 : -1) * (int) ((__builtin_classify_type (data) == 14 || __builtin_classify_type (data) == 5) ? sizeof (void *) : sizeof (data))), [_SDT_A1] "nor" ((data)), [_SDT_S2] "n" (((!(__builtin_classify_type (len) == 14 || __builtin_classify_type (len) == 5) && __sdt_type<__typeof (len)>::__sdt_signed) ? 1 : -1) * (int) ((__builtin_classify_type (len) == 14 || __builtin_classify_type (len) == 5) ? sizeof (void *) : sizeof (len))), [_SDT_A2] "nor" ((len)), [_SDT_S3] "n" (((!(__builtin_classify_type ((k)->class_loader()) == 14 || __builtin_classify_type ((k)->class_loader()) == 5) && __sdt_type<__typeof ((k)->class_loader())>::__sdt_signed) ? 1 : -1) * (int) ((__builtin_classify_type ((k)->class_loader()) == 14 || __builtin_classify_type ((k)->class_loader()) == 5) ? sizeof (void *) : sizeof ((k)->class_loader()))), [_SDT_A3] "nor" (((k)->class_loader())), [_SDT_S4] "n" (((!(__builtin_classify_type ((shared_class)) == 14 || __builtin_classify_type ((shared_class)) == 5) && __sdt_type<__typeof ((shared_class))>::__sdt_signed) ? 1 : -1) * (int) ((__builtin_classify_type ((shared_class)) == 14 || __builtin_classify_type ((shared_class)) == 5) ? sizeof (void *) : sizeof ((shared_class)))), [_SDT_A4] "nor" (((shared_class)))); __asm__ __volatile__ (".ifndef _.stapsdt.base" "\n" ".pushsection .stapsdt.base" "," "\"aG\"" "," "\"progbits\"" "," ".stapsdt.base" "," "comdat" "\n" ".weak _.stapsdt.base" "\n" ".hidden _.stapsdt.base" "\n" "_.stapsdt.base: .space 1" "\n" ".size _.stapsdt.base" "," "1" "\n" ".popsection" "\n" ".endif" "\n"); } while (0); };
