2016-02-02Store estimated istrances in compressed_sizeH.J. Lu2-15/+29
elf_x86_64_convert_load is very time consuming since it is called on each input section and has a loop over input text sections to estimate the branch distrance. We can store the estimated distrances in the compressed_size field of the output section, which is only used to decompress the compressed input section. Before the patch, linking clang 3.9 takes 52 seconds. After the patch, it only takes 2.5 seconds. PR ld/19542 * elf64-x86-64.c (elf_x86_64_convert_load): Store the estimated distrances in the compressed_size field of the output section.

2016-02-02opcodes/cgen: Rework calculation of shift when inserting fieldsAndrew Burgess15-42/+157
The calculation of the shift amount, used to insert fields into the instruction buffer, is not correct when the following conditions are all true: - CGEN_INT_INSN_P is defined, and true. - CGEN_INSN_LSB0_P is true - Total instruction length is greater than the length of a single instruction word (the instruction is made of multiple words) - The word offset is non-zero (the field is outside the first word) When the above conditions are all true, the calculated shift fails to take account of the total instruction length. After this commit the calculation of the shift amount is split into two parts, first we calculate the shift required to get to BIT0 of the word in which the field lives, then we calculate the shift required to place the field within the instruction word. The change in this commit only effects the CGEN_INT_INSN_P defined true case, but changes the code for both CGEN_INSN_LSB0_P true, and false. In the case of CGEN_INSN_LSB0_P being false, the code used to say: shift = total_length - (word_offset + start + length); Now it says: shift_to_word = total_length - (word_offset + word_length); shift_within_word = word_length - start - length; shift = shift_to_word + shift_within_word; From which we can see that in all cases the computed shift value should be unchanged. In the case of CGEN_INSN_LSB0_P being true, the code used to say: shift = (word_offset + start + 1) - length; Now it says: shift_to_word = total_length - (word_offset + word_length); shift_within_word = start + 1 - length; shift = shift_to_word + shift_within_word; In the case where 'total_length == word_length' AND 'word_offset == 0' (which indicates an instruction of a single word), we see that the computed shift value will be unchanged. However, when the total_length and word_length are different, and the word_offset is non-zero then the computed shift value will be different (and correct). opcodes/ChangeLog: * cgen-ibld.in (insert_normal): Rework calculation of shift. * epiphany-ibld.c: Regenerate. * fr30-ibld.c: Regenerate. * frv-ibld.c: Regenerate. * ip2k-ibld.c: Regenerate. * iq2000-ibld.c: Regenerate. * lm32-ibld.c: Regenerate. * m32c-ibld.c: Regenerate. * m32r-ibld.c: Regenerate. * mep-ibld.c: Regenerate. * mt-ibld.c: Regenerate. * or1k-ibld.c: Regenerate. * xc16x-ibld.c: Regenerate. * xstormy16-ibld.c: Regenerate.

2016-02-02epiphany/gas: Update expected test results for 0 offset loadsAndrew Burgess4-14/+21
In commit 02a79b89fdeadccb67048291e6c2a1e5ce6ad623 some of the load instructions with a zero offset (where the offset is not mentioned) were marked as NO-DIS, meaning that the disassembler must display the offset, even though it is zero. This change seems a little strange to me as it was only applied to some loads, not all, and the same change was not applied to the stores. However, I'm reluctant to revert a specific change to the assembler, when the output is obviously correct. With this commit then I simply bring the expected assembler test results into line with what is actually produced. gas/ChangeLog: * testsuite/gas/epiphany/addr-syntax.d: Add explicit 0 offset to some load instructions. * testsuite/gas/epiphany/allinsn.d: Likewise. * testsuite/gas/epiphany/regression.d: Likewise.

2016-02-02Adaptation of siginfo fixup for the new bnd fieldsWalfred Tedeschi3-102/+240
New bnds fields will be always present for x86 architecture. Fixup for compatibility layer 32bits has to be fixed. It was added the nat_siginfo to serving as intermediate step between kernel provided siginfo and the fix up routine. When executing compat_siginfo_from_siginfo or compat_x32_siginfo_from_siginfo first the buffer read from the kernel are converted into the nat_signfo for homogenization, then the fields of nat_siginfo are use to set the compat and compat_x32 siginfo fields. In other to make this conversion independent of the system where gdb is compiled the most complete version of the siginfo, named as native siginfo, is used internally as an intermediate step. Conversion using nat_siginfo is exemplified below: compat_siginfo_from_siginfo or compat_x32_siginfo_from_siginfo: buffer (from the kernel) -> nat_siginfo -> 32 / X32 siginfo (memcpy) (field by field) siginfo_from_compat_x32_siginfo or siginfo_from_compat_siginfo: 32 / X32 siginfo -> nat_siginfo -> buffer (to the kernel) (field by field) (memcpy) Caveat: No support for MPX on x32. 2016-02-02 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/ChangeLog: * amd64-linux-siginfo.c (nat_siginfo_t, nat_sigval_t, nat_timeval): New types.

2016-02-01gdb: Guard against undefined behaviour in mi-vla-fortran.expAndrew Burgess2-16/+38
The test gdb.mi/mi-vla-fortran.exp reveals an issue with the DWARF generated by gfortran. In the test a pointer variable 'pvla2' is created: real, pointer :: pvla2 (:, :) Initially this variable will be unassociated, so something like this: l = associated(pvla2) should return false. In the test gdb stops at a point _before_ pvla2 is associated with anything, and we then try to print pvla2, the expectation is that gdb should reply <not associated>. The problem is that the data the DWARF directs gdb to read (to identify if the variable is associated or not) is not initialised until the first time pvla2 is accessed. As a result gdb ends up reading uninitialised memory, sometimes this uninitialised memory indicates the variable is associated (when it's not). This first mistake can lead to a cascade of errors, reading uninitialised memory, with the result that gdb builds an invalid type to associate with the variable pvla2. In some cases, this invalid type can be very large, which when we try to print pvla2 causes gdb to allocate a large amount of memory. A recent commit added a new gdb variable 'max-value-size', which prevents gdb from allocating values of extreme size. As a result directly trying to print pvla2 will now now error rather than allocate a large amount of memory. However, some of the later tests create a varobj for pvla2, and then ask for the children of that varobj to be displayed. In the case where an invalid type has been computed for pvla2 then the number of children can be wrong, and very big, in which case trying to display all of these children can cause gdb to consume an excessive amount of memory. This commit first detects if printing pvla2 triggers the max-value-size error, if it does then we avoid all the follow on tests relating to the unassociated pvla2, which avoids the second error printing the varobj children. gdb/testsuite/ChangeLog: * gdb.mi/mi-vla-fortran.exp: Add XFAIL for accessing unassociated pointer. Don't perform further tests on the unassociated pointer if the first test fails.
2016-02-01gdb: New set/show max-value-size command.Andrew Burgess9-4/+289
For languages with dynamic types, an incorrect program, or uninitialised variables within a program, could result in an incorrect, overly large type being associated with a value. Currently, attempting to print such a variable will result in gdb trying to allocate an overly large buffer. If this large memory allocation fails then the result can be gdb either terminating, or (due to memory contention) becoming unresponsive for the user. A new user visible variable in gdb helps guard against such problems, two new commands are available: set max-value-size show max-value-size The 'max-value-size' is the maximum size of memory in bytes that gdb will allocate for the contents of a value. Any attempt to allocate a value with a size greater than this will result in an error. The initial default for this limit is set at 64k, this is based on a similar limit that exists within the ada specific code. It is possible for the user to set max-value-size to unlimited, in which case the old behaviour is restored. gdb/ChangeLog: * value.c (max_value_size): New variable.
