* MFC r304928:kib2016-09-031-57/+0
| | | | | | | | | | | | | Do not obliterate errno value in the main thread during ptrace(2) call on x86. MFC r304931: Follow ABI when calling __error from the ptrace(2) wrapper. MFC r305012: Rewrite ptrace(2) wrappers in C. MFC r305022: Restore the requirement of setting errno to zero before calling ptrace(2).
* libc/i386: Do not export .cerror.jilles2012-09-051-4/+1
| | | | | | | | | | | | | | | | | | | | | | | For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit in the FBSDprivate_1.0 version. It looks like there is no reason for this since it is not used from other libraries. Given that it cannot be accessed from C and its strange calling convention, it is rather unlikely that other things rely on it. Perhaps it is from a time when symbols could not be hidden. Not exporting .cerror causes it to be jumped to directly instead of via the PLT. This change also takes advantage of .cerror's new status by not saving and loading %ebx before jumping to it. (Therefore, .cerror now saves and loads %ebx itself.) Where there was a conditional jump to a jump to .cerror, the conditional jump has been changed to jump to .cerror directly (many modern CPUs don't do static prediction and in any case it is not much of a benefit anyway). This change makes libc.so.7 a few kilobytes smaller. Reviewed by: kib

| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.
* Add support to enable libc to be compiled in ELF format. (#ifdef __ELF__)peter1996-05-051-6/+7
| | | | | | | | | | | In a nutshell, this macroizes the local/global symbol scoping rules that are different in a.out and ELF. It also makes the i386 assembler stubs conform to i386 PIC calling conventions - the a.out ld.so didn't object, but the ELF one needs it as it implements PIC jumps via PLT's as well as calls. The a.out rtld only worked because it was accidently snooping the grandparent calling function's return address off the stack.. This also affects the libc_r code a little, because of cpp macro nesting.
