Make functions and variables exported by the IPA be extern "C" Functions and variables that are exported by the IPA DSO (that GDBserver needs to look up) should have "C" mangling, thus be declared with extern "C". Function and variable declarations need the extern "C" marker, but variable definitions can't be marked extern, so the patch splits IP_AGENT_EXPORT into three. Building in C++ mode revealed that a few variables were missing IP_AGENT_EXPORT, thus the IPA has been broken when stripped, even in C mode...

[PR gdb/13808] gdb.trace: Pass tdesc selected in gdbserver to IPA. If gdbserver and IPA are using different tdesc, they will disagree about 'R' trace packet size. This results in mangled traces. To make sure they pick the same tdesc, gdbserver pokes the tdesc (specified as an index in a target-specific list) into a global variable in IPA. In theory, IPA could find out the tdesc on its own, but that may be complex (in particular, I don't know how to tell whether we have LAST_BREAK on s390 without messing with ptrace), and we'd have to duplicate the logic. Tested on i386 and x86_64. On i386, it fixes two FAILs in ftrace.exp. On x86_64, these failures have been KFAILed - one of them works now, but the other now fails due to an unrelated reason (ugh). gdb/gdbserver/ChangeLog: PR gdb/13808 * Makefile.in: Add i386-*-linux-ipa.o and amd64-*-linux-ipa.o. * configure.srv: Ditto. * linux-aarch64-ipa.c (get_ipa_tdesc): New function.

IPA: Add alloc_jump_pad_buffer target hook. Targets may have various requirements on the required location of the jump pad area. Currently IPA allocates it at the lowest possible address, so that it is reachable by branches from the executable. However, this fails on powerpc, which has executable link address (0x10000000) much larger than branch reach (+/- 32MiB). This makes jump pad buffer allocation a target hook instead. The current implementations are as follows: - i386 and s390: Branches can reach anywhere, so just mmap it. This avoids the linear search dance. - x86_64: Branches have +/-2GiB of reach, and executable is loaded low, so just call mmap with MAP_32BIT. Likewise avoids the linear search. - aarch64: Branches have +-128MiB of reach, executable loaded at 4MiB. Do a linear search from 4MiB-size downwards to page_size. - s390x: Branches have +-4GiB of reach, executable loaded at 2GiB. Do like on aarch64. gdb/gdbserver/ChangeLog: * linux-aarch64-ipa.c: Add <sys/mman.h> and <sys/auxv.h> includes. (alloc_jump_pad_buffer): New function. * linux-amd64-ipa.c: Add <sys/mman.h> include.

Make functions and variables exported by the IPA be extern "C" Functions and variables that are exported by the IPA DSO (that GDBserver needs to look up) should have "C" mangling, thus be declared with extern "C". Function and variable declarations need the extern "C" marker, but variable definitions can't be marked extern, so the patch splits IP_AGENT_EXPORT into three. Building in C++ mode revealed that a few variables were missing IP_AGENT_EXPORT, thus the IPA has been broken when stripped, even in C mode...

/* The prototype the get_raw_reg function in the IPA. Each arch's

gdbserver/IPA: Export some functions via global function pointers. On powerpc64, qSymbol for a function returns the function code address, and not the descriptor address. Since we emit code calling gdb_collect and some other functions, we need the descriptor (no way to know the proper TOC address without it).
