From: H.J. Lu Date: Wed, 8 Jun 2016 19:41:50 +0000 (-0700) Subject: i386: Test external function reference without PLT X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ffc89b17f2a432389ef15485fa887231a0d2b6c3;p=binutils-gdb.git i386: Test external function reference without PLT To call an external function, the direct branch to the PLT entry can be replaced by an indirect branch via the GOT slot, which is similar to the first instruction in the PLT slot. Instead using the PLT slot as function address, the function address is retrieved from the GOT slot. The R_386_GOT32X relocation can be used to compute the address of the symbol’s GOT entry without base register when PIC is disabled. In non-PIC executable, call/jmp *func@GOT should be used for indirect branch via the GOT slot and movl func@GOT, %eax should be used to load function address. Unlike PIC case, no register is needed to access GOT. If linker determines the function is defined locally, it converts indirect branch via the GOT slot to direct branch with a nop prefix and converts load via the GOT slot to load immediate or lea. * testsuite/ld-i386/libno-plt-1b.dd: New file. * testsuite/ld-i386/libno-plt-1b.rd: Likewise. * testsuite/ld-i386/no-plt-1a.dd: Likewise. * testsuite/ld-i386/no-plt-1a.rd: Likewise. * testsuite/ld-i386/no-plt-1b.dd: Likewise. * testsuite/ld-i386/no-plt-1b.rd: Likewise. * testsuite/ld-i386/no-plt-1c.dd: Likewise. * testsuite/ld-i386/no-plt-1c.rd: Likewise. * testsuite/ld-i386/no-plt-1d.dd: Likewise. * testsuite/ld-i386/no-plt-1d.rd: Likewise. * testsuite/ld-i386/no-plt-1e.dd: Likewise. * testsuite/ld-i386/no-plt-1e.rd: Likewise. * testsuite/ld-i386/no-plt-1f.dd: Likewise. * testsuite/ld-i386/no-plt-1f.rd: Likewise. * testsuite/ld-i386/no-plt-1g.dd: Likewise. * testsuite/ld-i386/no-plt-1g.rd: Likewise. * testsuite/ld-i386/no-plt-1h.dd: Likewise. * testsuite/ld-i386/no-plt-1h.rd: Likewise. * testsuite/ld-i386/no-plt-1i.dd: Likewise. * testsuite/ld-i386/no-plt-1i.rd: Likewise. * testsuite/ld-i386/no-plt-1j.dd: Likewise. * testsuite/ld-i386/no-plt-1j.rd: Likewise. * testsuite/ld-i386/no-plt-check1a.S: Likewise. * testsuite/ld-i386/no-plt-check1b.S: Likewise. * testsuite/ld-i386/no-plt-extern1a.S: Likewise. * testsuite/ld-i386/no-plt-extern1b.S: Likewise. * testsuite/ld-i386/no-plt-func1.c: Likewise. * testsuite/ld-i386/no-plt-main1.c: Likewise. * testsuite/ld-i386/no-plt.exp: Likewise. --- diff --git a/ld/testsuite/ld-i386/libno-plt-1b.dd b/ld/testsuite/ld-i386/libno-plt-1b.dd new file mode 100644 index 00000000000..507ed16217f --- /dev/null +++ b/ld/testsuite/ld-i386/libno-plt-1b.dd @@ -0,0 +1,19 @@ +#objdump: -dwrj.text +#target: i?86-*-* + +.*: +file format elf32-i386.* + +Disassembly of section .text: + +#... +[0-9a-f]+ : + +[a-f0-9]+: e8 ([0-9a-f]{2} ){4}[ ]+call +[a-f0-9]+ <__x86.get_pc_thunk.ax> + +[a-f0-9]+: 05 ([0-9a-f]{2} ){4}[ ]+add +\$0x[a-f0-9]+,%eax + +[a-f0-9]+: 8b 80 ([0-9a-f]{2} ){4}[ ]+mov +-0x[a-f0-9]+\(%eax\),%eax + +[a-f0-9]+: c3 ret +#... +[0-9a-f]+ : + +[a-f0-9]+: e8 ([0-9a-f]{2} ){4}[ ]+call +[a-f0-9]+ <__x86.get_pc_thunk.ax> + +[a-f0-9]+: 05 ([0-9a-f]{2} ){4}[ ]+add +\$0x[a-f0-9]+,%eax + +[a-f0-9]+: ff a0 ([0-9a-f]{2} ){4}[ ]+jmp +\*-0x[0-9a-f]+\(%eax\) +#pass diff --git a/ld/testsuite/ld-i386/libno-plt-1b.rd b/ld/testsuite/ld-i386/libno-plt-1b.rd new file mode 100644 index 00000000000..6881a2db993 --- /dev/null +++ b/ld/testsuite/ld-i386/libno-plt-1b.rd @@ -0,0 +1,8 @@ +#readelf: -Wr +#target: i?86-*-* + +Relocation section '.rel.dyn' at offset 0x[0-9a-f]+ contains [0-9]+ entries: + +Offset +Info +Type +Sym.
