We have to tell gc those 3 asm's use gp, because otherwise when optimizing there might be a gp value from last called function in gp instead of current function's got pointer. 2003-04-01 Jakub Jelinek <jakub at redhat dot com> * elf/tls-macros.h [__ia64__] (TLS_IE, TLS_LD, TLS_GD): Add gp register as input to asm. --- libc/elf/tls-macros.h.jj 2003-03-02 06:41:54.000000000 -0500 +++ libc/elf/tls-macros.h 2003-04-01 14:31:13.000000000 -0500 @@ -316,13 +316,14 @@ register void *__gp __asm__("$29"); # define TLS_IE(x) \ ({ void *__l; \ + register long __gp asm ("gp"); \ asm (";;\n\t" \ "addl r16= at ltoff(@tprel(" #x ")),gp\n\t" \ ";;\n\t" \ "ld8 r17=[r16]\n\t" \ ";;\n\t" \ "add %0=r13,r17\n\t" \ - : "=r" (__l) : : "r16", "r17" ); __l; }) + : "=r" (__l) : "r" (__gp) : "r16", "r17" ); __l; }) # define __TLS_CALL_CLOBBERS \ "r2", "r3", "r8", "r9", "r10", "r11", "r14", "r15", "r16", "r17", \ @@ -335,6 +336,7 @@ register void *__gp __asm__("$29"); # define TLS_LD(x) \ ({ void *__l; \ + register long __gp asm ("gp"); \ asm (";;\n\t" \ "mov loc0=gp\n\t" \ "addl r16= at ltoff(@dtpmod(" #x ")),gp\n\t" \ @@ -345,11 +347,12 @@ register void *__gp __asm__("$29"); ";;\n\t" \ "mov gp=loc0\n\t" \ "mov %0=r8\n\t" \ - : "=r" (__l) : : "loc0", __TLS_CALL_CLOBBERS); \ + : "=r" (__l) : "r" (__gp) : "loc0", __TLS_CALL_CLOBBERS); \ __l; }) # define TLS_GD(x) \ ({ void *__l; \ + register long __gp asm ("gp"); \ asm (";;\n\t" \ "mov loc0=gp\n\t" \ "addl r16= at ltoff(@dtpmod(" #x ")),gp\n\t" \ @@ -361,7 +364,7 @@ register void *__gp __asm__("$29"); ";;\n\t" \ "mov gp=loc0\n\t" \ "mov %0=r8\n\t" \ - : "=r" (__l) : : "loc0", __TLS_CALL_CLOBBERS); \ + : "=r" (__l) : "r" (__gp) : "loc0", __TLS_CALL_CLOBBERS); \ __l; }) #elif defined __sparc__ && !defined __arch64__ Jakub
