2024-02-26Add ability to serialize compilation/linking in cc rulesBoris Kolpackov1-0/+10
Specifically, both the C/C++ compiler and link rules now recognize the cc.serialize boolean variable which instructs them to compiler/link serially with regards to any other recipe. This is primarily useful when compiling large translation units or linking large binaries that require so much memory that doing that in parallel with other compilation/linking jobs is likely to summon the OOM killer. For example: obj{memory-hog}: cc.serialize = true
2024-02-15Add fsdir{} duplicate suppression in more placesBoris Kolpackov1-1/+2
2024-01-09Disable use of -frewrite-includes for assembler with preprocessor filesBoris Kolpackov1-3/+24
With -frewrite-includes Clang has issues with correctly tracking location information (manifests itself as wrong line numbers in debug info, for example). The result also appears to reference the .Si file instead of the original source file for some reason. While at it also omit trying to scan such files since that can be hazardous (such files sometimes use `#`-style comments).

2023-09-11Invoke Clang to produce object files for module partitions similar to interfacesSwat SomeBug1-2/+7
Module interface and implementation partitions are like module interfaces so it's not surprising they require similar compilation steps. See GH PR #328 for background.

2023-04-18Add support for Assembler with C Preprocessor (.S) compilationBoris Kolpackov1-31/+42
Specifically, the c module now provides the c.as-cpp submodules which can be loaded in order to register the S{} target type and enable Assembler with C Preprocessor compilation in the c compile rule. For details, refer to "Assembler with C Preprocessor Compilation" in the manual.
2023-04-10Fix inconsistent /usr/local/{include,lib} searchBoris Kolpackov1-6/+7
In particular, we were adding -L/usr/local/lib which means it is considered before built-in directories (/usr/lib, etc) but in our own library search code we were considering it after (because we were storing it at the end of sys_lib_dirs). Now in both sys_{hdr,lib}_dirs we store /usr/local/{include,lib} after mode and before built-in directories. Note that as part of this fix we now pass -isystem /usr/local/include instead of -idirafter (which is consistent with the -L behavior and also the customarily expected semantics).

This is used by bpkg to detect forwarded configurations without incurring the full context creation overhead.

2022-10-10Preparatory work for public/private variable distinctionBoris Kolpackov1-0/+4
We still always use the public var_pool from context but where required, all access now goes through scope::var_pool().
