2019-09-05[c-family] Backport fix for PCH / PR61250.Iain Sandoe8-10/+48
When we are parsing a source file, the very first token might be a PRAGMA_GCC_PCH_PREPROCESS. This indicates that we are going read in a PCH file (named as the value of the pragma). If we don't see this pragma, then we know that it's OK to release any resources that the host might have set aside for the PCH file. There is a thinko in the current implementation, in that the decision to release resources is happening unconditionally right after the first token is extracted but before it's been checked or acted upon. This leads to the pch bug on Darwin, because we actually do release resources - which are subsequently (reasonably) assumed to be available when reading a PCH file. We then get random crashes or hangs depending on the interaction between unmmap and malloc. The bug is present everywhere but doesn't show on (say) Linux, since the release of PCH resources is a NOP there. This effects all the c-family front ends, because they all use c_lex_with_flags () to implement this. The solution is to check for the PRAGMA_GCC_PCH_PREPROCESS and only call c_common_no_more_pch () when that is not the first token. A secondary effect of the collection is that the name of the PCH file can be collected during the ggc_pch_read() reset of state. Therefore we should issue any diagnostic that might name the file before the collections are triggered. gcc/ 2019-09-05 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * ggc-page.c (ggc_pch_read): Read the ggc_pch_ondisk structure and issue any diagnostics needed before collecting the pre-PCH state. gcc/c-family/ 2019-09-05 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * c-lex.c (c_lex_with_flags): Don't call c_common_no_more_pch () from here. gcc/c 2019-09-05 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline. 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * c-parser.c (c_parse_file): Call c_common_no_more_pch () after determining that the first token is not PRAGMA_GCC_PCH_PREPROCESS. gcc/cp/ 2019-09-05 Iain Sandoe <iain@sandoe.co.uk> Backported from mainline 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * parser.c (cp_parser_initial_pragma): Call c_common_no_more_pch () after determining that the first token is not PRAGMA_GCC_PCH_PREPROCESS.

2019-09-05[Darwin] Fix PR87030 and tidy config fragments.Iain Sandoe12-30/+211
This is about 32/64b host and multilib support across the range of Darwin systems. Prior to Darwin8 (OS X 10.4), the toolchains support only PowerPC and only 32b. On Darwin8 it is possible to target a 64b multilib, but with support limited to a few of the main libraries on the system (not a recommended configuration). From Darwin9 to Darwin17 (OSX 10.5 to 10.13) it is possible to have either 32 or 64b hosted toolchains, with support for a 64 or 32b multilib respectively. On Darwin9 the kernel is 32b, but with support for 64b executables, so it's conventional to build a 32b host toolchain supporting a 64b multilib. However this is not enforced (merely a convention). There is also some platform hardware supporting Darwin10/11 which is only 32b and for which the same situation applies. However, from Darwin10 to Darwin17, the majority of platform hardware supports a 64b kernel and it's conventional to build a 64b host toolchain with support for a 32b multilib. On/from Darwin18 (OS X 10.14), the development headers (in the SDK) no longer expose the interfaces for the 32b multilib support (although sufficient runtime support remains installed that the testsuite can be run for a 32b multilib). The PR is raised against this latter situation since the absence of exposed interfaces causes a 'default' bootstrap fail regardless of the availability of the runtimes. Given the number of permutations, I felt it warranted a general solution, especially since the current scheme of target headers and t-make fragments has become somewhat messy. The changes here enforce the single 32b PowerPC multilib for Darwin < 8 and the single X86 64b multilib for Darwin >= 18. This means that there is no longer any need to configure Darwin18+ '--disable-multilib', but also that if you want to use the ability to continue to test the compiler's 32b multilib there, you need to make a configuration targeting an earlier OS version (and using the SDK from that). 2019-09-05 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-07-24 Iain Sandoe <iain@sandoe.co.uk> PR bootstrap/87030 * config/i386/darwin.h (REAL_LIBGCC_SPEC): Revert change from r273749.

2019-09-04[Darwin] Make a final check on PIC options.Iain Sandoe2-2/+13
Final check on PCI options; for Darwin these are not dependent on the PIE ones, although PIE does require PIC to support it. Specifically, for Darwin, '-fPIC -fno-PIE' should result in the same as '-fno-PIE -fPIC'. This is a workaround for the situation in which a 'stock-built' GCC is unable to bootstrap m32 Darwin unless it's done '-mdynamic-no-pic'. So this fixes a bootstrap fail in that case. 2019-09-04 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-07-07 Iain Sandoe <iain@sandoe.co.uk> * config/darwin.c (darwin_override_options): Make a final check on PIC options.

2019-09-04[Darwin, Driver] Fix driver crashes with valid command line input.Iain Sandoe4-22/+171
Backport Improve processing of macosx-version-min= For PR target/63810 some improvements were made in the parsing of the version string at the point it's used to define the built-in __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__. This is fine, but the specs processing also uses the version, and specs version-compare doesn't like leading zeros on components. This means that while we succeed in processing -mmacosx-version-min=010.00002.000099 on compile lines, it fails for any other line that uses the value as part of a spec (in particular, link lines fail). To fix this, we need to apply a bit of clean-up to the version that's presented to the driver, and push that back into the command line opts. The value can come from four places: 1. User-entered on the command line 2. User-entered as MACOSX_DEPLOYMENT_TARGET= environment var. 3. Absent those two 3a For self-hosting systems, look-up from the kernel 3b For cross-compilers, as a default supplied at configure time. We apply the clean-up to all 4 (although it shouldn't really be needed for the cases under 3). We also supply a test-case that adapts to the target-version of the system, so that the link requirements are met by the SDK in use (if you try to link i686-darwin9 on an x86-64-darwin18 SDK, it will fail). gcc/ 2019-09-04 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-06-19 Iain Sandoe <iain@sandoe.co.uk> * config/darwin-driver.c (darwin_driver_init): Fix off-by-one errors in computing the number of options to be moved.

2019-09-03[Darwin, Objective-C] Don't prepend a sysroot for the gnu-objc headers.Iain Sandoe2-24/+24
Darwin is able to use two runtimes for objective-c; the default is its native NeXT runtime, but also it can build code using the gnu-runtime. In order to do this, we have to be able to find the gnu-runtime headers (which are installed into the compiler's tree). The process to do this was erroneously prepending the sysroot to this when a sysroot is in force. The gnu-runtime headers have never been installed in a Darwin (MacOS) SDK so we must make sure that they are found local to the compiler. 2019-09-03 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-05-18 Iain Sandoe <iain@sandoe.co.uk> * config/darwin-c.c (darwin_register_objc_includes): Do not prepend the sysroot when building gnu-runtime header search paths.
